Reaction Steps

Under argon and at 0° C., a 2-molar solution of hydrogen chloride in diethyl ether (370 ml) is added dropwise to a solution of tert-butyl 4-[4-(ethoxycarbonyl)-1,3-thiazol-2-yl]piperidine-1-carboxylate (25.0 g) in diethyl ether (200 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-(ethoxycarbonyl)-1,3-thiazol-2-yl]piperidinium chloride (20.0 g, 98%)
