Procedure

Tert-butyl (trans)-4-aminocyclohexylcarbamate (1.500 g) and triethylamine (2.93 mL, 2.125 g) were added to dichloromethane and stirred until the tert-butyl (trans)-4-aminocyclohexylcarbamate had dissolved completely. Acetyl chloride (0.577 g) was added slowly, and the solution was stirred at room temperature for 16 hours. The solvent was removed, and the residue taken up in ethyl acetate, washed with pH 4 buffer, washed with brine, dried with anhydrous sodium sulfate, and filtered. The filtrate was concentrated under vacuum.
