実験手順
The title compound was prepared by a similar method to Preparation 3 from ethyl (2S)-1-(1,3-benzothiazol-2-yl)-2-piperidinecarboxylate [see Preparation 42] and 1N aqueous lithium hydroxide solution. The crude product was purified by column chromatography on silica gel eluting with a solvent system of 10:1, by volume, dichloromethane:methanol to afford (2S)-1-(1,3-benzothiazol-2-yl)-2-piperidinecarboxylic acid as a solid.
