Abstract
A process for the preparation of (S) -2- (4-chlorophenyl) isovalerate of (R, S) -alpha-cyano-3-phenoxybenzyl containing a higher proportion of (S) -2- (4-chlorophenyl) isovalerate of (S) -alpha-cyano-3-phenoxybenzyl involving the crystallization of (S) -2- (4-chlorophenyl) isovalerate from (S) -alpha-cyano-3-phenoxybenzyl from a solution of (S) - 2- (4-chlorophenyl) isovalerate of (R, S) -alpha-cyano-3- phenoxybenzyl in a solvent, in the presence of a basic substance in order to increase the proportion of (S) -2- (4- chlorophenyl) (S) -alpha-cyano-3-phenoxybenzyl isovalerate in the porridge, and recovery of the product resulting from crystallization together with (S) -2- (4-chlorophenyl) isovalerate of (R, S) -alpha- cyano-3-phenoxybenzyl in the mother liquor.
