A method for the synthesis of the title compound and a resolution method are reported here. L-(+)-tartaric acid was used as resolving agent. Optimum resolution process conditions were: 30°, 5 h, a mixture of acetone and methanol solvent volume ratio 1:4 and the mol ratio of α-amino-2-chlorobenzeneacetic acid Me ester to L-(+)-tartaric 1:1.1. The resolution process provide a yield above 90% (optical rotation 88°). This process may have industrial applications. The above-mentioned title compound is an intermediate in the synthesis of clopidogrel. This study involved multiple reactions and reactants, such as (S)-Methyl 2-amino-2-(2-chlorophenyl)acetate (cas: 141109-14-0Product Details of 141109-14-0).
(S)-Methyl 2-amino-2-(2-chlorophenyl)acetate (cas: 141109-14-0) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Product Details of 141109-14-0
