실험 절차
t-Butyl 3-(4-(cyclopropylamino)thieno[3,2-d]pyrimidine-7-carboxamido)-4-methylphenylcarbamate (7 g, 15.93 mmol) was dissolved in DCM (80 mL), TFA (12 mL, 159.3 mmol) was added thereto, and the mixture was stirred at room temperature for 8 hours. After the reaction was completed, the reaction mixture was concentrated under reduced pressure to remove the organic solvent and the remaining TFA, and water (20 mL) was added thereto. The reaction mixture was neutralized with 2.0 N NaOH solution, and the resulting yellow solid was filtered and dried to obtain the title compound without further purification.
