Reaction Steps

To a solution of tert-butyl 4-{4-[5-(2-acetylphenyl)-4,5-dihydro-1,2-oxazol-3-yl]-1,3-thiazol-2-yl}piperidine-1-carboxylate (500 mg) in 1,4-dioxane (5 ml) was added dropwise, at 0° C., a 4 molar solution of hydrogen chloride in 1,4-dioxane (4.2 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 1-(2-{3-[2-(piperidin-4-yl)-1,3-thiazol-4-yl]-4,5-dihydro-1,2-oxazol-5-yl}phenyl)ethanone hydrochloride (430 mg).
