Procedure
Dissolve 4-[4-(cyclopropylmethyl-amino)-pyrimidin-2-yl]-N-(tert-butoxycarbonyl)-benzylamine (100 mg, 0.28 mmol) in DCM (3 mL) containing trifluoroacetic acid (2 mL). Stir under nitrogen for 3 h. Concentrate in vacuo and purify the crude mixture by SCX chromatography (5 g) to obtain the title compound (68.5 mg, 90%) suitable for use without additional purification. MS (ES+) m/z: 255 (M+H)+.
