Synthetic Route of 104-11-0, A common heterocyclic compound, 104-11-0, name is 1-(4-Chlorophenyl)-N-methylmethanamine, molecular formula is C8H10ClN, its 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.
PREPARATION EXAMPLE 8 Preparation of 1-(4-chlorobenzyl)-1,3-dimethyl-3-[2-methyl-1-(4-trifluoromethyl-pyrimidin-5-yl)-propyl]-urea (compound No. 1-532 of the present invention) 0.16g (1.0 mmol) of (4-chlorobenzyl)-methylamine was dissolved in 30 ml of pyridine, and 0.3g (1.0 mmol) of N-methyl-N-[2-methyl-1-(4-trifluoromethyl-pyrimidin-5-yl)-propyl]-carbamoyl chloride was dropwise added, followed by stirring at room temperature for 10 hours. To the reaction solution, 50 ml of water was added, followed by extraction with diethyl ether. The obtained organic phase was washed twice with 30 ml of a dilute citric acid aqueous solution, followed by drying over anhydrous magnesium sulfate. Diethyl ether was distilled off under reduced pressure, and the obtained crude product was purified by silica gel chromatography (developing solvent/n-hexane:ethyl acetate=8:1 to 3:1) to obtain0.22g (yield: 52%) of 1-(4-chlorobenzyl)-1,3-dimethyl-3-[2-methyl-1-(4-trifluoromethyl-pyrimidin-5-yl)-propyl]-urea as colorless crystals (melting point: 95-98C).
The synthetic route of 104-11-0 has been constantly updated, and we look forward to future research findings.
