A straightforward and efficient asymmetric synthesis of (S)-1-[4-(2-methoxyphenyl)piperazin-1-yl]-3-(3,4,5-trimethoxyphenoxy)propan-2-ol is described. The key intermediate, (S)-2-[(3,4,5-trimethoxyphenoxy)methyl]oxirane, was obtained by a hydrolytic kinetic resolution method using the catalyst (R,R)-salen-cobalt(III) complex. trimethoxyphenol - resolution - chiral epoxide - methoxybenzenamine
