실험 절차

Hydrogen chloride (4N, 1.5 ml) in ethyl acetate was added to a solution of (2S)-2-(4-piperidin-1-yl-phenyl)-piperazine-1,4-dicarboxylic acid di-tert-butyl ester (455 g, 1.02 mmol) in dichloromethane (10 ml) and the solution was stirred for 2 hours. Filtration and washing with ethyl acetate of the precipitant gave (2S)-2-(4-piperidin-1-yl-phenyl)-piperazine trihydrochloride (353 mg, 98%) as white crystals.
