Procedure

N-Chlorosuccinimide (0.92 g, 6.89 mmol) was added to an N,N-dimethylformamide solution (60 ml) of tert-butyl {5-[9-(cyclopropylmethyl)-6-morpholin-4-yl-9H-purin-2-yl]pyrimidin-2-yl}methylcarbamate (2.14 g, 4.59 mmol) at room temperature. The resulting mixture was stirred for 4.5 hours followed by the addition of N-chlorosuccinimide (0.12 g, 0.92 mmol) and the resulting mixture was further stirred for 2.5 hours. The reaction mixture was poured into ethyl acetate, washed with water, and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure and the resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=17:3 to 3:1) to give the title compound (1.29 g, 56%, two steps combined) as a colorless amorphous substance.
