To a solution of 2-isopropyl-4-{(E)-2-[3-(methoxymethoxy)-1-phenyl-1H-pyrazol-4-yl]ethenyl}-1,3-thiazole (1.47 g) in methanol (20 mL) was added concentrated hydrochloric acid (0.5 mL) at room temperature, and the mixture was stirred at room temperature for 20 hrs. The reaction mixture was evaporated under reduced pressure, and the residue was washed with ethyl acetate-hexane to give 4-[(E)-2-(2-isopropyl-1,3-thiazol-4-yl)ethenyl]-1-phenyl-1H-pyrazol-3-ol hydrochloride (1.43 g, yield 99%) as pale-yellow crystals. melting point: 137-139° C.
