Temperature: 150 °C

Procedure

N-Methylpyrrolidone (1 ml) was added to 5-[8-chloro-9-(cyclopropylmethyl)-6-morpholin-4-yl-9H-purin-2-yl]-4-(trifluoromethyl)pyrimidin-2-amine (75 mg, 0.16 mmol) and N-methanesulfonylpiperazine (135 mg, 0.8 mmol) and the resulting mixture was stirred at 150° C. for 7 hours. The reaction mixture was partitioned with ethyl acetate and water and the organic layer was washed with saturated brine and dried over magnesium sulfate. The solvent was evaporated under reduced pressure and then the residue was purified by preparative HPLC (column, NOMURA Develosil Combi-RP-5; mobile phase, acetonitrile/water/formic acid) to give the title compound (45 mg, 47%) as a white solid.
