US9199930: Process for the preparation of (s)-2-ethyl-n-(1-methoxypropan-2-yl)-6-methyl aniline

Disclosed herein is a novel process for the preparation of (S)-2-ethyl-N-(1-methoxypropan-2-yl)-6-methyl aniline [(S)-1]. Particularly, the invention relates to the synthesis of (S)-2-ethyl-N-(1-methoxypropan-2-yl)-6-methyl aniline with excellent selectivity starting from commercially available enantiopure (R)-epichlorohydrin [(R)-2] via formation of aziridine intermediate [(S)-4].
