실험 절차

Into a dry reaction vessel, ethyl 2-[2-methyl-3-[4-[4-(trifluoromethyl)benzamido]benzyl]-1H-indol-1-yl]acetate (600 mg, 1.21 mmol), lithium hydroxide monohydrate (153 mg, 3.64 mmol), 10 mL tetrahydrofuran, 10 mL methanol, 10 mL water were weighed, 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. It was filtered, and the filter cake was washed with 20 mL methanol to obtain the product 480 mg as a white solid, at a yield of 85.1%.
