Participants

Reaction Steps

By a method similar to Example 31, using 4-methoxybenzenesulfonyl chloride (248 mg, 1.2 mmol) and 3-(1-methylpiperidin-4-yl)-5-hydroxy-1H-indole (230 mg, 1.0 mmol), 0.2 N sodium hydroxide (5.5 mL, 1.1 mmol) gave 225 mg of crude product. The crude product was recrystallized from ethyl acetate to give 195 mg (49%) of the title compound as a white powder: mp=186-187° C.; MS(m/e): 400 (M+); Calculated for C21H24N2O4S: Calcd: C, 62.98; H, 6.04; N, 6.99. Found: C, 63.10; H, 6.18; N, 7.04.
