The title compound was prepared by a similar method to Example 5 from (2S)-1-(1,3-benzoxazol-2-yl)-N2-[(3S)-pyrrolidin-3-yl]-2-piperidinecarboxamide [see Example 4] and 2-bromoacetamide. The crude product was purified by column chromatography on silica gel eluting with a solvent gradient of 93:7:1, changing to 90:10:1, by volume, dichloromethane:methanol: 0.88 aqueous ammonia solution to afford (2S)-N2-[(3S)-1-((aminocarbonyl)methyl)pyrrolidin-3-yl]-1-(1,3-benzoxazol-2-yl)-2-piperidinecarboxamide as an oil.
