Reaction Steps

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) (60 mg, 0.2 mmol) and 4-methylbenzyl carbonochloridate (63.5 mg, 0.22 mmol) according to General Procedure H to give 20 mg (22.3%) of white solid.
