実験手順
To a solution of tert-butyl 2-chloro-5-cyano-3-(4-methylpiperazin-1-yl)phenylcarbamate (135 mg, 0.385 mmol) in DCM (1.4 mL) was added TFA (0.6 mL, 3.89 mmol). The mixture was stirred at reaction mixture. The solvent was evaporated under vacuum, the residue was dissolved in EtOAc, washed with small amount of sat NaHCO3, and brine, dried over MgSO4, filtered, concentrated, and the residue was purified by ISCO (12 g, EtOAc/DCM=0-60%) to give 82 mg of 3-amino-4-chloro-5-(4-methylpiperazin-1-yl)benzonitrile
