Reaction Steps

Pyridinium chlorochromate (266 mg, 1.23 mmol) and sodium acetate (20 mg, 0.247 mmol) were added to a methylene chloride (24 mL) solution of N-{2-{[(2R)-2-hydroxypropyl]amino}-2-oxo-1-[4-(trifluoromethoxy)benzyl]ethyl}-4-(3,3,3-trifluoropropoxy)benzamide (322 mg, 0.616 mmol) prepared in Example 74. The mixture was stirred at room temperature for 8 hours, and water (60 mL) was added thereto. The resulting mixture was extracted with methylene chloride (50 mL, three times). The organic layer was dried over anhydrous sodium sulfate, concentrated, and purified by alumina column chromatography (ethyl acetate:methanol, 9:1, V/V) to give 299 mg of the title compound (white powder, yield: 93%).
