2,5-Dichlorobenzooxazole → benzyl(2S)-1-(5-chloro-1,3-benzoxazol-2-yl)-2-piperidinecarboxylate

Participants

Reaction Steps

The title compound was prepared by a similar method to Preparation 2 from (2S)-2-[(benzyloxy)carbonyl]piperidinium chloride [see EP 530167 A1 930303] and 2,5-dichloro-1,3-benzoxazole [see J.O.C. (1996), 61(10), 3289-3297]. The crude product was purified by column chromatography on silica gel eluting with a solvent system of 95:5, by volume, hexane:ethyl acetate to afford benzyl (2S)-1-(5-chloro-1,3-benzoxazol-2-yl)-2-piperidinecarboxylate as an oil.
