Diisopropylethylamine → 5-{8-[4-(Methylsulfonyl)piperidin-1-yl]-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-2-yl}pyrimidin-2-amine

Reaction Conditions

Reaction Steps

4-Methanesulfonylpiperidine hydrochloride (385 mg, 1.93 mmol), diisopropylethylamine (672 μl, 3.9 mmol), and N-methyl-2-pyrrolidone (2 ml) were added to 5-[8-chloro-6-morpholin-4-yl-9-(2,2,2-trifluoroethyl)-9H-purin-2-yl]pyrimidin-2-amine (200 mg, 0.48 mmol) and the resulting mixture was stirred at 100° C. for 12 hours. The reaction mixture was partitioned with ethyl acetate and water, the organic layer was dried over magnesium sulfate, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel chromatography (chloroform:methanol=20:1) to give the title compound (81 mg, 33%) as a pale yellow solid.
