Procedure

Triethylamine (80.3 μl, 0.58 mmol) was added to a methylene chloride solution (3.0 ml) of 5-{9-(cyclopropylmethyl)-8-[(3S)-3-methylpiperazin-1-yl]-6-morpholin-4-yl-9H-purin-2-yl}pyrimidin-2-amine (108.1 mg, 0.24 mmol) at room temperature followed by the addition of acetic anhydride (27.2 μl, 0.29 mmol) with ice cooling. The resulting mixture was stirred at room temperature for 2 hours and then the reaction mixture was poured into methylene chloride-methanol (10:1), 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 medium pressure silica gel column chromatography (methylene chloride:methanol=49:1 to 19:1) to give the title compound (115.8 mg, 98%) as a pale yellow solid.
