Reference of 623-12-1,Some common heterocyclic compound, 623-12-1, name is 1-Chloro-4-methoxybenzene, molecular formula is C7H7ClO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.

The appropriate quantity of stock solution C was added to a 4 mL vial containing the aryl chloride (1.00 mmol) and potasium terf-butoxide (123 mg, 1.10 mmol) in 1.5 mL of toluene. The aromatic thiol (1.00 mmol) was then added, and the vial sealed with a cap containing a PTFE septum. The mixture was heated at 110 0C until the chloroarene was consumed, as determined by GC. Silica gel (0.5 g) was then added, and solvents were evaporated under reduced pressure. The crude residue was purified by column chromatography on silica gel using hexane or a mixture of hexane and ethyl acetate as eluent. Aryl sulfides were isolated in the yields reported in Table 4.4-Methoxyphenyl phenyl sulfide (Table 4, entry 1).[49] 100 muL of stock solution C were used. A 50:1 mixture of hexane/ethyl acetate was used as chromatography eluent. 98% yield. Colorless liquid. 1H NMR (CDCl3): delta = 7.23 (d, J= 8.8 Hz5 2H), 7.06-7.02 (m, 2H), 7.00-6.93 (m, 3H), 6.71 (d, J= 8.8 Hz5 2H)5 3.62 (s, 3H). 13C NMR (CDCl3): delta = 159.7, 138.5, 135.3 (2C), 128.8 (2C), 128.1 (2C), 125.7, 124.2, 114.9 (2C)5 55.3.

The synthetic route of 623-12-1 has been constantly updated, and we look forward to future research findings.

Adding a certain compound to certain chemical reactions, such as: 4535-90-4, name is 2-Chloro-N-methylethanamine hydrochloride, belongs to chlorides-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 4535-90-4, category: chlorides-buliding-blocks

A mixture of iraw5,-8-chloro-l-[4-(3-fluoro-pyridin-2-yl)-cyclohexyl]-5,6-dihydro-4H-2,3,5,10b- tetraaza-benzo[e]azulene (50.0 mg, 0.126 mmol), cesium carbonate (246 mg, 0.754 mmol) and 2-methylaminoethyl chloride hydrochloride (65.4 mg, 0.503 mmol) in acetonitrile (1.3 ml) was heated at 70 C for 20 h. After addition of further portions of cesium carbonate (246 mg, 0.754 mmol) and 2-methylaminoethyl chloride hydrochloride (65.4 mg, 0.503 mmol) the mixture was heated at 70 C for another 20 h. The reaction mixture was partitioned between 1 M aqueous sodium hydroxide solution (2 ml) and ethyl acetate (5 ml). The layers were separated. The aqueous layer was extracted with two 5-ml portions of ethyl acetate. The combined organic layers were concentrated in vacuo. Preparative RP-HPLC with water (0.05% formic acid) / methanol as eluent gave the title compound as formate salt. The salt was partitioned between ethyl acetate (15 ml) and 1 M aqueous sodium hydroxide solution (10 ml). The layers were separated. The aqueous layer was extracted with two 15 ml-portions of ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate and concentrated in vacuo to give the title compound (14 mg, 25%) as off-white solid. MS m/e: 455 ([M+H]+)

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Chloro-N-methylethanamine hydrochloride, other downstream synthetic routes, hurry up and to see.

Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 104-77-8, name is 3-Chloro-N,N-diethylpropan-1-amine, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 104-77-8

a Phenylmethyl 1-[3-(diethylamino)propyl]-1H-indole-3-acetate At a temperature of about +50 C., 6.2 g (44.9 mMol) of potassium carbonate were added to a solution of 4.0 g (15.1 mMol) of phenylmethyl 1H-indole-3-acetate in 40 ml of dimethylformamide and then at the same temperature a solution of 3.0 g (20.0 mMol) of 3-(diethylamino)propylchloride in 5 ml of dimethylformamid were added dropwise. The mixture was stirred for a further hour at 50 C. and overnight at ambient temperature, heated up to 100 C. again and once more 1.0 g of 3-(diethylamino)propylchloride were added. After stirring for 5 hours at ambient temperature, the mixture was stirred into 300 ml of ice water and extracted exhaustively with diisopropylether. The combined organic extracts were washed with saturated saline solution, dried over magnesium sulphate, clarified with activated charcoal and evaporated down under reduced pressure. A colourless oil was obtained in a yield of 5.37 g (94% of theory) and was used in the following step without further purification. MS: M+ =378

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 104-77-8.
