N-methyl-2-pyrrolidone → 5-{9-Isobutyl-8-[4-(methylsulfonyl)-1,4-diazepan-1-yl]-6-morpholin-4-yl-9H-purin-2-yl}pyrimidin-2-amine

温度

120 °C

Homopiperazine (130 mg, 1.3 mmol) and N-methylpyrrolidone (1 ml) were added to 5-(8-chloro-9-isobutyl-6-morpholin-4-yl-9H-purin-2-yl)pyrimidin-2-amine (100 mg, 0.26 mmol) and the resulting mixture stirred at 120° C. for 2 hours. The reaction mixture was cooled and partitioned with methylene chloride and water, the organic layer was dried over magnesium sulfate, and the solvent was concentrated under reduced pressure. Triethylamine (110 μl) and mesyl chloride (45 μl, 0.58 mmol) were added to the resulting mixture and the resulting mixture was stirred for 0.5 hours. The reaction mixture was partitioned with ethyl acetate and water and the organic layer was dried over magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by preparative HPLC (column, NOMURA Develosil Combi-RP-5; mobile phase, acetonitrile/water/formic acid) to give the title compound (153 mg, 75%) as a white solid.
