実験手順

1-Hydroxybenzotriazole (33.2 mg, 0.25 mmol), N,N′-dicyclohexylcarbodiimide (76.1 mg, 0.37 mmol), and triethylamine (102.8 μl, 0.75 mmol) were added to an N,N-dimethylformamide (3.0 ml)-methylene chloride (3.0 ml) mixture solution of 5-{9-(cyclopropylmethyl)-8-[(3R)-3-methylpiperazin-1-yl]-6-morpholin-4-yl-9H-purin-2-yl}pyrimidin-2-amine (110.8 mg, 0.25 mmol) and D-lactic acid (26.9 mg, 0.30 mmol) at room temperature. The resulting mixture was stirred for 18.5 hours followed by the addition of N,N′-dicyclohexylcarbodiimide (76.1 mg, 0.37 mmol) and the resulting mixture stirred at 40° C. for 22 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 (98.1 mg, 76%) as a pale yellow solid.
