The title compound was prepared by a similar method to Preparation 3 from (2S)-1-[(cyclohexylmethyl)sulfonyl]-2-piperidinecarboxamide [see Preparation 26], oxalyl chloride, dimethylformamide and pyridine. The crude product was purified by column chromatography on silica gel eluting with a solvent gradient of 80:20 changing to 20:80, by volume (in 10% increments), hexane:ethyl acetate to afford (2S)-1-[(cyclohexylmethyl)sulfonyl]-2-piperidinecarbonitrile as an oil.
