Procedure

tert-Butyl piperidin-3-ylmethylcarbamate (500 mg) was dissolved in anhydrous dichloromethane (10 mL), and methanesulfonyl chloride (0.181 mL) was added followed by the addition of triethylamine (1.3 mL). The reaction mixture was stirred at room temperature overnight. The organic solvent was removed under vacuum. The residue was purified with flash column chromatography on silica gel eluting with 0-70% ethyl acetate in hexane to give the title compound.
