실험 절차

To a solution of 2-(4-((S)-3-(aminomethyl)piperidin-1-yl)-7-methylquinazolin-2-yl)phenol (175 mg, 0.5 mmol) in DMF at 0° C. were added (S)-tetrahydrofuran-3-yl chloroformate (75 mg, 0.5 mmol) and triethylamine (137 μL, 1.0 mmol) simultaneously. Ten to fifteen minutes after addition, the reaction was complete, and it was quenched with water and extracted with CH2Cl2. The combined organic layers were dried over MgSO4, filtered, and concentrated. Purification via silica gel chromatography using 98% CH2Cl2/2% MeOH gave (S)-tetrahydrofuran-3-yl ((S)-1-(2-(2-hydroxyphenyl)-7-methylquinazolin-4-yl)piperidin-3-yl)methylcarbamate (150 mg, 54%). LC/MS: m/z 463.5 (M+H)+ at 2.37 min (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)).
