Procedure

The title compound was prepared by a similar method to Example 1 from (2S)-1-[5,6-dimethyl-1,3-benzoxazol-2-yl]-2-piperidinecarboxylic acid [see Preparation 53] and 2-[(cis)-2,6-dimethyl-1-piperidinyl]ethylamine [J.Med.Chem., 27(5), (1984), 684-691]. The crude product was purified by column chromatography on silica gel, eluting with a solvent gradient of 93:7:1, by volume, dichloromethane: methanol: 0.88 aqueous ammonia solution to afford (2S)-N-2-[(cis)-2,6-dimethyl-1-piperidinyl]ethyl-1-[1-(5,6-dimethyl-1,3-benzoxazol-2-yl]-2-piperidinecarboxamide as a white solid.
