Trifluoroacetic acid → 13-cyclohexyl-6-(1-cyclopropyl-4-(ethoxycarbonyl)-3-isopropyl-1H-pyrazol-5-yl)-3-methoxy-7H-indolo[2,1-a][2]benzazepine-10-carboxylic Acid

Participants

Reaction Steps

TFA (2.8 mL, 37 mmol) was added to a stirring solution of tert-butyl 13-cyclohexyl-6-(1-cyclopropyl-4-(ethoxycarbonyl)-3-isopropyl-1H-pyrazol-5-yl)-3-methoxy-7H-indolo[2,1-a][2]benzazepine-10-carboxylate (350 mg, 0.527 mmol) in dichloroethane (5 mL) at room temperature. The reaction was allowed to stir for 2.5 hrs and then was concentrated to dryness to give expected product (320 mg, 0.526 mmol, quant) consistent by LCMS.
