Conditions

Temperature: 140 °C

Procedure

Dimethyl sulfoxide (1 ml) was added to 5-{8-chloro-9-[(3S)-1-(methylsulfonyl)pyrrolidin-3-yl]-6-morpholin-4-yl-9H-purin-2-yl}pyrimidin-2-amine (100 mg, 0.21 mmol) and cis-2,6-dimethylpiperazine (119 mg, 1.04 mmol) and the resulting mixture was stirred at 140° C. for 1 hour. The reaction mixture was partitioned with chloroform 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=9:1) to give the title compound (95 mg, 82%) as a light brown solid.
