Procedure

Triethylamine (72.8 μl, 0.52 mmol) and acetic anhydride (24.6 μl, 0.26 mmol) were added to a methylene chloride solution (3.0 ml) of 5-[8-(3,3-dimethylpiperazin-1-yl)-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-2-yl]pyrimidin-2-amine (107.2 mg, 0.22 mmol) with ice cooling. The resulting mixture was stirred at room temperature for 2 hours followed by the addition of acetic anhydride (4.1 μl, 0.04 mmol) with ice cooling and the resulting mixture was stirred at room temperature for 4.5 hours. The reaction mixture was poured into methylene chloride-methanol (10:1), washed with saturated aqueous sodium hydrogen carbonate solution, and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure and the resulting residue was purified by preparative thin layer silica gel chromatography (methylene chloride:methanol=10:1) to give the title compound (102.6 mg, 88%) as a pale yellow solid.
