실험 절차

Under argon and at 0° C., a 2-molar solution of hydrogen chloride in diethyl ether (50 ml) is added dropwise to a solution of tert-butyl 4-{4-[(cyclohexyloxy)carbonyl]-1,3-thiazol-2-yl}piperidine-1-carboxylate (XXXIII-1, 2.63 g) in dioxane (20 ml). The reaction mixture is stirred at 0° C. and then slowly warmed to room temperature. After stirring overnight, the solvent and excess hydrogen chloride are removed. This gives 4-{4-[(cyclohexyloxy)carbonyl]-1,3-thiazol-2-yl}piperidinium chloride (2.19 g, 99%).
