Versuchsvorschrift

To a stirred solution of tert-butyl 3-(5-amino-6-(dibenzylamino)pyrimidin-4-ylamino)phenyl(methyl)carbamate (22) (3.1 g, 6.08 mmol) and TEA (1.75 mL, 12.16 mmol) in dry DCM (40 mL) at 0° C. and under N2 atmosphere was added a solution of triphosgene (722 mg, 2.43 mmol) in dry DCM (20 mL) dropwise during 1 h. After the stirring was continued for 1 h, the reaction was quenched with water (10 mL). The organic layer was separated, washed with water and brine, dried over Na2SO4, and concentrated in vacuo. The residue was purified by column chromatography (silica gel, 0 to 20% ethyl acetate in petroleum ether) to give tert-butyl 3-(6-(dibenzylamino)-8-oxo-7H-purin-9(8H)-yl)phenyl(methyl)carbamate (23) (3 g, 92%) as a light brown solid. LC-MS (ESI): m/z (M+1) 537.
