実験手順

2-(2-chloro-5-bromo-pyrimidin-4-ylamino)-N-methyl-benzamide (52 mg, 0.15 mmol) and 7-amino-1-methyl-1,3,4,5-tetrahydrobenzo[b]azepin-2-one (29 mg, 0.15 mmol) were combined in 5 mL n-butanol. A drop of a solution of 4N hydrochloric acid in dioxane was added and the mixture was refluxed for five hours. The mixture was concentrated and triturated with ether. The remaining solid was partitioned between dichloromethane and saturated sodium bicarbonate solution (100 mL each). The organic layer was separated, was dried (sodium sulfate), and was concentrated to afford an oil which was purified on silica (methanol:dichloromethane gradient elution) to afford 36 mg (48%) of 2-[5-bromo-2-(1-methyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-7-ylamino)-pyrimidin-4-ylamino]-N-methyl-benzamide as an off-white solid. Mp: 238-40° C.; MS: 496.61 (M+H); 1H NMR (chloroform-d): δ 10.95 (s, 1H), δ 8.58 (d, J=8 Hz, 1H), δ 8.22 (s, 1H), δ 7.52 (d, J=8 Hz, 1H), δ 7.44 (m, 3H), δ 7.11 (t, J=8 Hz, 1H), δ 7.01 (s, 1H), δ 6.25 (br s, 1H), δ 3.35 (s, 3H), δ 3.06 (s, 3H), δ 2.67 (m, 2H), δ 2.33 (t, J=7 Hz, 2H), δ 2.16 (m, 2H).
