実験手順
A solution of ethyl N-tert-butoxycarbonyl-4-[3-(methane-sulfonylaminomethyl)benzyl]piperidine-4-carboxylate (270 mg) in dichloromethane (40 mL) at 0° C. was saturated with hydrogen chloride gas. The resultant solution was sealed with a rubber septum and stirred at room temp. for 2.5 h. The product solution was concentrated under vacuum to provide the title compound
