To a suspension of 2-{[4-phenyl-5-(phenylthio)-1,3-thiazol-2-yl]methyl}-1H-isoindole-1,3(2H)-dione (0.53 g) in ethanol (5 mL) was added hydrazine monohydrate (0.1 mL), and the mixture was stirred at 70° C. for 1 hr. The reaction mixture was cooled to room temperature, water was added, and the mixture was extracted with ethyl acetate. The extract was washed with saturated aqueous sodium hydrogen carbonate solution, water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to give the title compound as a yellow oil (yield 0.36 g, 97%).
