To a solution of 7-Amino-6-methoxy-1-methyl-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (50 mg, 0.227 mmol) and 2-(2,5-Dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (56 mg, 0.189 mmol) in 2.27 mL of 2-methoxyethanol was added 57 μL of 4M HCl in Dioxane (0.227 mmol). The solution was heated to 110° C. for 5 hrs, followed by the addition of MP-Carbonate (135 mg, 0.43 mmol) at RT. The MP-Carbonate was filtered after 30 minutes and the resulting crude material was chromatographed (ISCO) to give 2-[5-Chloro-2-(6-methoxy-1-methyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-7-ylamino)-pyrimidin-4-ylamino]-N-methyl-benzamide (23 mg, 25%). 1H-NMR (CDCl3) δ 11.12 (s, 1H), 8.66 (d, J=8.6 Hz, 1H), 8.26 (d, J=8.8 Hz, 1H), 8.14 (s, 1H), 7.51 (t, J=7.7 Hz, 2H), 7.43 (s, 1H), 7.12 (t, J=7.6 Hz, 1H), 6.90 (t, J=8.8 Hz, 1H), 6.26 (br s, 1H), 3.80 (s, 3H), 3.33 (s, 3H), 3.04 (s, 3H), 2.0-2.4 (m, 6H); LC/MS (ESI-pos) m/z 481.06 (M+H).
