Reaction Steps
Phenyl (1R,2R)-2-((S)-1-(4-nitrophenyl)piperidin-3-ylamino)cyclohexylcarbamate was synthesized using (1R,2R)—N1-(1-(4-nitrophenyl)piperidin-3-yl)cyclohexane-1,2-diamine (from intermediate C, Example 2) (30 mg, 0.094 mmol) and phenyl carbonochloridate (14.75 mg, 0.094 mmol) according to General Procedure G to give 5 mg (10% yield) of the product as a yellow solid.
