Procedure

To a solution of 6-chloro-5-[3-fluoro-4-(2-hydroxyethoxy)phenyl]-1H-indole-3-carbaldehyde (40 mg, 0.12 mmol) in water (1 mL) and t-butanol (1 mL) was added sodium chlorite (210 mg, 2.30 mmol), 2-methyl-2-butene (0.5 mL) and sodium dihydrogen phosphate (350 mg, 2.90 mmol). The reaction solution was stirred at room temperature for 10 hrs. The reaction was diluted with water (5 mL) and extracted with dichloromethane (20 mL×3). The combined organic phase was washed with water (20 mL), brine (20 mL), dried over sodium sulfate and concentrated to give a crude product. The crude was purified by preparative HPLC to give the title compound (20 mg, 49% yield) as off-white solid. MS (AP−) 348.0 (M−H)−. 1H NMR (400 MHz, CD3OD) δ 8.05 (s, 1H), 8.01 (s, 1H), 7.60 (s, 1H), 7.20 (m, 3H), 4.21 (t, 2H), 3.95 (t, 2H).
