Conditions

Temperature: 150 °C

Procedure

Dimethyl sulfoxide (1 ml) was added to a mixture of 5-[8-chloro-6-morpholin-4-yl-9-(tetrahydrofuran-3-ylmethyl)-9H-purin-2-yl]pyrimidin-2-amine (100 mg, 0.24 mmol) and morpholine (63 μl, 0.72 mmol) and the resulting mixture was stirred at 150° C. for 3 hours. The reaction mixture was cooled and then partitioned with chloroform and water, and the organic layer was washed again with water and then dried over magnesium sulfate. The solvent was evaporated under reduced pressure and then the residue was purified by silica gel chromatography (chloroform:methanol=10:0 to 25:1 to 20:1) to give the title compound (75 mg, 67%) as a pale yellow solid.
