Procedure

A dimethyl sulfoxide suspension (5 ml) of 5-[8-chloro-9-(cyclopropylmethyl)-6-morpholin-4-yl-9H-purin-2-yl]pyrimidin-2-amine (476.1 mg, 1.23 mmol) and (2S)-2-methylpiperazine (616.4 mg, 6.15 mmol) was heated at 100° C. to dissolve and the resulting mixture was stirred at 85° C. for 18.5 hours. (2S)-2-Methylpiperazine (123.3 mg, 1.23 mmol) was added and the resulting mixture was further stirred at 85° C. for 5.5 hours, left standing to cool, poured into methylene chloride-methanol (10:1), and washed with saturated aqueous sodium hydrogen carbonate solution. The organic layer was dried over anhydrous sodium sulfate, the mixture was filtrated, the filtrate was concentrated under reduced pressure, and the resulting residue was purified by medium pressure silica gel column chromatography (methylene chloride:methanol=32:1 to 9:1) to give the title compound (516.0 mg, 93%) as a pale yellow solid.
