実験手順

A suspension of 4-(6-chloro-5-methylpyrimidin-4-yl)-7-(2-methyl-1H-imidazo[4,5-b]pyridin-6-yl)-2,3,4,5-tetrahydro-1,4-benzoxazepine (44 mg, 0.11 mmol), and ethylamine (29 mg, 0.65 mmol), in N-methylpyrrolidinone (2 mL) was stirred at 100° C. for 6 h. The reaction mixture was diluted with ethyl acetate (75 mL), washed with saturated sodium bicarbonate (75 mL) and brine (50 mL), and dried over sodium sulfate. Concentration and purification by preparatory HPLC (0.1% aqueous ammonium acetate-acetonitrile) gave N-ethyl-5-methyl-6-[7-(2-methyl-1H-imidazo[4,5-b]pyridin-6-yl)-2,3-dihydro-1,4-benzoxazepin-4(5H)-yl]pyrimidin-4-amine (13 mg, 30% yield) as a white solid. 1H NMR (400 MHz, CD3OD) δ 8.50 (s, 1H), 8.07 (s, 1H), 8.04 (d, 1H), 7.56-7.48 (m, 2H), 7.11 (d, 1H), 4.57 (s, 2H), 4.33 (d, 2H), 3.79 (d, 2H), 3.53-3.39 (q, 2H), 2.64 (s, 3H), 2.04 (s, 3H), 1.21 (t, 3H); MS (EI) for C23H25N7O: 416 (MH+).
