Versuchsvorschrift

To a mixture of methyl[2-(4-aminobenzyl)-4-(dimethylamino)pyrimidin-5-yl]acetate (1.50 g, 4.99 mmol) in pyridine (1.21 mL) and dichloromethane (20 mL) was added benzyl chloroformate (1.07 mL, 7.49 mmol). After stirring for 14 hours at room temperature, the reaction mixture was concentrated under reduced pressure. The remaining residue was chromatographed on silica gel (NH silica gel, hexane/ethyl acetate 2:1) to give methyl[2-(4-{[(benzyloxy)carbonyl]amino}-benzyl)-4-(dimethylamino)pyrimidin-5-yl]acetate (1.99 g, 92%).
