Participants

Reaction Steps

Acetic anhydride (0.035 ml, 0.38 mmol) was added dropwise to a methylene chloride solution (6 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 (123 mg, 0.25 mmol) and triethylamine (0.069 ml, 0.50 mmol) with ice cooling and the resulting mixture was stirred at room temperature for 1.5 hours. The resulting mixture was partitioned with ethyl acetate and saturated aqueous ammonium chloride solution and the organic layer was washed with 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=95:5) to give the title compound (92 mg) as a pale yellow solid.
