실험 절차

To a solution of 2-ethyl-4-{(E)-2-[3-(methoxymethoxy)-1-phenyl-1H-pyrazol-4-yl]ethenyl}-5-methyl-1,3-thiazole (3.21 g) in methanol (75 mL) was added concentrated hydrochloric acid (1.5 mL) at room temperature, and the mixture was stirred at 50° C. for 2 hrs. The reaction mixture was evaporated under reduced pressure, and the residue was washed with ethyl acetate-methanol to give 4-[(E)-2-(2-ethyl-5-methyl-1,3-thiazol-4-yl)ethenyl]-1-phenyl-1H-pyrazol-3-ol.hydrochloride (3.02 g, yield 96%) as pale-yellow prism crystals. melting point: 184-186° C.
