Reaction Steps

31 g) 2-(2,5-Dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (650 mg/2.2 mmol), 3-Ethyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (500 mg/2.6 mmol) and 4 N HCl in dioxane (650 μL/2.6 mmol) were suspended in 2-methoxyethanol (5 mL) and heated to 120° C. until judged complete by HPLC. The resulting tan solution was cooled to room temperature, diluted with methanol (2 mL) and treated with solid potassium carbonate (carbon dioxide evolves). The mixture was filtered and the filtrate concentrated onto silica gel and purified by column chromatography to afford 2-[5-Chloro-2-(3-ethyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino)-pyrimidin-4-ylamino]-N-methyl-benzamideas a tan solid (200 mg/20%). 1H NMR (400 MHz, CDCl3) δ 11.02 (s, 1H), 8.68 (d, J=8.1 Hz, 1H), 8.06 (s, 1H), 7.52-7.40 (m, 2H), 7.33 (s, 1H), 7.23 (s, 1H), 7.09-6.98 (m, 2H), 6.87 (s, 1H), 6.20 (s, 1H), 3.05 (d, J=3.8 Hz, 3H), 2.91 (m, 4H), 2.60 (m, 6H), 1.11 (t, J=6.9 Hz, 3H). LC/MS found 451 (M+H). mp 201° C.
