Abstract

The present invention relates to process for optical resolution of 2-hydroxy-3- methoxy-3,3-diphenylpropanoic acid. Thus, for example, reacting racemic 2-hydroxy-3- methoxy-3,3-diphenylpropanoic acid with S-(-)-1-(1-naphtyl)ethylamine in acetone to obtain corresponding diastereomer salts. The diastereomeric salts were subjected to fractional crystallization to obtain (S)-2-hydroxy-3-methoxy-3,3-diphenylpropanoic acid ,S-(-)-1-(1-naphthyl)ethylamine. The separated isomer was dissolved in a mixture of water and methyl tert-butyl ether and pH was adjusted to 1.1 with concentrated hydrochloric acid to obtain (S)-2-hydroxy-3-methoxy-3,3-diphenylpropanoic acid.
