Reaction Steps

Ethyl (2-{7-(benzyloxy)-5-[4-(methylsulfonyl)phenoxy]-1H-indol-2-yl}-4,5-dihydro-1,3-thiazol-5-yl)acetate (1.0 g) was dissolved in a mixed solvent of tetrahydrofuran (6 mL)-ethanol (6 mL), 1M aqueous sodium hydroxide solution (6 mL) was added, and the mixture was stirred at room temperature for 10 min. The reaction solution was concentrated under reduced pressure. Water was added to the residue, and the mixture was neutralized with 1M hydrochloric acid, and filtered. The obtained solid was washed successively with water, ethanol and diethyl ether to give the title compound (640 mg, yield 67%) as a pale-orange solid. The obtained solid was recrystallized from ethanol-hexane to give colorless crystals. melting point 218-219° C. MS 537 (MH+).
