Participants

Reaction Steps

1-Ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (80 mg, 0.42 mmol) was added to an N,N-dimethylformamide solution (5 ml) of 5-{8-[(3S)-3-ethylpiperazin-1-yl]-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-2-yl}pyrimidin-2-amine (136 mg, 0.28 mmol), triethylamine (0.096 ml, 0.69 mmol), L-lactic acid (30 mg, 0.33 mmol), and 1-hydroxybenzotriazole (47 mg, 0.30 mmol) and the resulting mixture was stirred at room temperature for 16 hours. The resulting mixture was partitioned with ethyl acetate and saturated aqueous ammonium chloride solution and the organic layer 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=95:10) to give the title compound (31 mg) as a pale yellow solid.
