Reaction Steps

Suspend the 3-amino-2-carbethoxy-6-trifluoromethylindole (290 mg, 1.06 mmol) in tetrahydrofuran (30 mL) and add triethylamine (0.150 mL, 1.17 mmol). Add benzoyl chloride (0.136 mL, 1.17 mmol) and stir for 30 minutes at room temperature. Dilute the reaction with ethyl acetate rinse with 1M HCl, water, dry over magnesium sulfate, filter and concentrate in vacuo. Recrystallize from hot ethyl acetate/hexane to yield 3-[(phenacyl)amino]-2-carbethoxy-6-trifluoromethylindole (230 mg, 56%); mp 237°-239° C.
