Reaction Steps

Into a dry reaction vessel, ethyl 2-[3-[4-(2-naphthamido)benzyl]-2-methyl-1H-indol-1-yl]acetate (530 mg, 1.11 mmol), lithium hydroxide monohydrate (140 mg, 3.34 mmol), 5 mL tetrahydrofuran, 5 mL methanol, 10 mL water were added successively, and stirred at room temperature for 1 h. The reaction was monitored to be complete by TLC. The solvent was rotate evaporated. It was adjusted to pH=3-4 with 2 N HCl solution. A solid precipitated, and was washed with ethyl acetate, dichloromethane, acetonitrile to obtain the product 100 mg as a white solid, at a yield of 20.1%.
