Reaction Steps

1-Ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (72.4 mg, 0.38 mmol) was added to an N,N-dimethylformamide solution (5 ml) of 5-{8-[(3R)-3-ethylpiperazin-1-yl]-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-2-yl}pyrimidin-2-amine (124 mg, 0.25 mmol), triethylamine (0.087 ml, 0.63 mmol), L-lactic acid (27.2 mg, 0.30 mmol), and 1-hydroxybenzotriazole (42.6 mg, 0.28 mmol), the resulting mixture was stirred at room temperature for 17 hours followed by the addition of 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (72.4 mg, 0.38 mmol), and the resulting mixture was stirred at 40° C. for 8 hours. The resulting mixture was partitioned with ethyl acetate and water and the organic layer was washed with water and saturated brine and dried over anhydrous sodium sulfate, the mixture was filtrated, the filtrate was concentrated under reduced pressure, and the resulting residue was purified by preparative thin layer silica gel chromatography (chloroform:methanol=90:10) to give the title compound (38.9 mg) as a pale yellow solid.
