Reaction Steps

2-Chloro-4-methylbenzyl (1R,2R)-2-((S)-1-(4-cyanophenyl)piperidin-3-ylamino)cyclohexylcarbamate was synthesized using 4-((S)-3-((1R,2R)-2-aminocyclohexylamino)piperidin-1-yl)benzonitrile (from intermediate D, Example 10) (50 mg, 0.17 mmol) and 2-chloro-4-methylbenzyl carbonochloridate (59.3 mg, 0.18 mmol) according to General Procedure H to give 20 mg (24.8%) of white solid.
