Glycolic Acid → 2-{4-[2-(2-Aminopyrimidin-5-yl)-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-8-yl]piperazin-1-yl}-2-oxoethanol

反応手順

2-Hydroxyacetic acid (15 mg, 0.19 mmol), hydroxybenzotriazole hydrate (37 mg, 0.19 mmol), 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (37 mg, 0.19 mmol), dimethylformamide (3 ml), and triethylamine (100 μl) were added to 5-[6-morpholin-4-yl-8-piperazin-1-yl-9-(2,2,2-trifluoroethyl)-9H-purin-2-yl]pyrimidin-2-amine trifluoroacetate (120 mg, 0.17 mmol) and the resulting mixture was stirred for 4 hours. The reaction mixture was partitioned with ethyl acetate and water, the organic layer was washed with saturated aqueous sodium bicarbonate solution and dried over magnesium sulfate, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (chloroform:methanol=19:1) to give the title compound (70 mg) as a colorless solid.
