Trifluoroacetic acid → HCID 70562875, compound

Participants

Reaction Steps

Trifluoroacetic acid (4 mL) was added rapidly dropwise to a stirred solution of methyl 2-(4-(tert-butoxycarbonylamino)-6-fluoro-1H-indol-1-yl)-2-(4-chlorophenyl)butanoate (0.92 g, 2 mmol) in DCM (10 mL) at 0° C. After 1 h, the reaction was quenched by careful addition of saturated aqueous sodium bicarbonate, followed by extraction with ether. The organic layers were washed with saturated aqueous sodium bicarbonate, dried over sodium sulfate, filtered and concentrated in vacuo to afford the title compound. LC/MS m/z=361.1 [M+H]+.
