13078-79-0, The chemical industry reduces the impact on the environment during synthesis 13078-79-0, name is 2-(3-Chlorophenyl)ethanamine, I believe this compound will play a more active role in future production and life.
At 0C, methyl chloroformate (4.6 g, 48 mmol) was added drop wise to a solution of 2-(3-chloro-phenyl)-ethylamine (5.0 g, 32 mmol) and Et3N (6.4 g, 64 mmol) in DCM (100 mL).After the addition, the mixture was stirred at room temperature for 0.5 hours. The organic layer was washed with water (3 x 30 mL), iN HC1 (20 mL) and brine (30 mL), dried over anhy. Na2SO4, filtered and concentrated in vacuo. After vacuum drying, the title compound was obtained (6.49 g, 95%) as a white solid. MS: 214.1 (M+H).
The chemical industry reduces the impact on the environment during synthesis 2-(3-Chlorophenyl)ethanamine. I believe this compound will play a more active role in future production and life.
