Trifluoroacetic acid → HCID 118024552, compound

Participants

Reaction Steps

TFA (3 mL) was slowly added to a stirred solution of tert-butyl (4-(4-isopropylpiperazin-1-yl)-2-nitrophenyl)carbamate (1.2 g, 3.29 mmol) in dry DCM (5 mL) under argon atmosphere at 0° C. The resulting reaction mixture was allowed to warm to room temperature and stirred for 12 hr. Reaction progress was monitored by LCMS, after completion of the reaction, excess solvents were removed under reduced pressure to afford a crude residue. The crude residue was repeatedly washed with ether to get the title compound (1 g, yield: 80.6%) as a red solid. MS (ESI): 265.1 [M+H]+.
