Participants

Reaction Steps

To a solution of 0.300 g (0.57 mmol) of N-(4-t-butoxycarbonylpiperazin-1-yl)-1-(4-chlorobenzoyl)-5-methoxy-2-methylindole-3-acetamide in 8 mL of anhydrous dichloromethane was added 1.7 mL of trifluoroacetic acid (TFA). The reaction was stirred at room temperature for 1.75 hr then evaporated to dryness, diluted with more dichloromethane (20 mL) and re-evaporated. Residual TFA was removed with a sodium carbonate wash to give the title compound. 1H NMR (CDCl3) δ 7.58 (2H, d), 7.41 (2H, d), 6.93 (1H, d), 6.73 (1H, d), 6.60 (1H, dd), 3.75 (3H, s), 3.64 (2H, s), 3.57 (2H, m), 3.42 (2H, m), 2.75 (2H, m), 2.67 (2H, m), 2.32 (3H, s).
