실험 절차
Dissolve 4-[6-(cyclopropylmethyl-amino)-pyrimidin-4-yl]-N-(tert-butoxycarbonyl)-benzylamine (450 mg, 1.2 mmol) in DCM (5 mL). Add trifluoroacetic acid (3 mL) and stir under nitrogen for 3 h. Concentrate in vacuo and purify the crude mixture by SCX chromatography (5 g) to obtain the title compound (305 mg, 93%) suitable for use without additional purification. MS (ES+) m/z: 255 (M+H)+.
