Reference of 63857-00-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 63857-00-1, name is N-((2-Chloro-3-((phenylimino)methyl)cyclohex-2-en-1-ylidene)methyl)aniline hydrochloride belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
16.4 g 2-mercapto-5-thiomethyl-1, 3, 4-THIADIAZOLE (available from FEW, Wolfen/Germany) and 36.0 g dye A (available from Aldrich) were added under stirring to 200 ML Downanol PM in a 11 three-necked flask equipped with a stirrer and a reflux condenser. Then a solution of 4.0 g sodium hydroxide and 36.5 g 2-methylene-1, 3, 3-trimethylindoline (Fischer base, available from Aldrich) in 35 ml ethanol was added under stirring for one minute to this suspension. The reaction mixture warmed up to about 40C without the addition of external heat. Then the reaction mixture was left to cool to room temperature and 600 ml of a 2 wt.-% hydrochloric acid were added. After the reaction mixture had cooled to room temperature, the insoluble portion was separated by filtration and washed with 21 of water. Then the product was dried for one day at 50C in a circulating air oven. Yield: 56.2 g (92.9% based on dye A). The dried product was suspended in 500 ML methyl ethyl ketone and heated to 80C for one hour. Subsequently, the solution with a temperature of about 40C was filtered and the solid portion was washed with ethyl acetate. The product was air-dried. Yield: 48.6 g (80.3 wt. – % based on dye A), W/VIS spectrum in methanol : No.MAX = 796 nm, extinction coefficient E = 3321/G X CM.
The synthetic route of N-((2-Chloro-3-((phenylimino)methyl)cyclohex-2-en-1-ylidene)methyl)aniline hydrochloride has been constantly updated, and we look forward to future research findings.
