Procedure

To tert-butyl 4-(4-formyl-1,3-thiazol-2-yl)piperidine-1-carboxylate (10 g) was added dropwise, at 0° C., a 4 molar solution of hydrogen chloride in 1,4-dioxane (100 ml). The reaction mixture was stirred at 0° C. and then gradually warmed to room temperature. After stirring overnight, the solvent and excess hydrogen chloride were removed. This gave 4-(4-formyl-1,3-thiazol-2-yl)piperidinium chloride (9 g).
