実験手順

2-(2-chloro-5-bromo-pyrimidin-4-ylamino)-N-methyl-benzamide (52 mg, 0.15 mmol) and 8-methoxy-3-(2-methoxyethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (48 mg, 0.19 mmol) were combined in 5 mL n-butanol. Two drops of a solution of 4N hydrochloric acid in dioxane was added and the mixture was refluxed for eight hours. The mixture was concentrated and the organics were 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 2-{5-bromo-2-[8-methoxy-3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino]-pyrimidin-4-ylamino}-N-methyl-benzamide as a tan foam (25%). Mp: 171-5° C.; MS: 556.78 (M+H); 1H NMR (chloroform-d): δ 10.81 (s, 1H), δ 8.60 (d, J=8 Hz, 1H), δ 8.21 (s, 1H), δ 8.08 (s, 1H), δ 7.53-7.41 (m, 3H), δ 6.92 (t, J=8 Hz, 1H), δ 6.66 (s, 1H), δ 6.24 (br s, 1H), δ 3.78 (s, 3H), δ 3.57 (t, J=5 Hz, 35), δ 3.39 (s, 3H), δ 3.06 (dd, J=2.4 Hz, 2H), δ 2.91 (m, 2H), δ 2.82-2.67 (m, 8H).
