実験手順

Under argon and at 0° C., a solution of hydrogen chloride in dioxane (4M, 1 ml) was added to a solution of tert-butyl 4-[4-(cyclohexylacetyl)-1,3-thiazol-2-yl]piperidine-1-carboxylate (5.0 g) in diethyl ether (1 ml). The mixture was stirred at 0° C. and then slowly warmed to room temperature. After stirring overnight, excess acid and the solvent were removed under reduced pressure. This gave 4-[4-(cyclohexylacetyl)-1,3-thiazol-2-yl]piperidinium chloride (315 mg).
