Procedure

2-(2,5-dichloro-pyrimidin-4-ylamino)-5-piperidin-1-yl-benzamide (50.1 mg, 0.137 mmol) and 7-amino-1-methyl-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (28.7 mg, 0.151 mmol) were slurried in methoxyethanol (2.0 mL) prior to adding ˜0.2 mL of 4N HCl in dioxane. This mixture was heated at 120° C. for 2 h. After quenching with saturated aqueous NaHCO3 solution (2 mL), the resulting precipitate was collected by filtration, successively washed water (5×2 mL) and ether (2×1 mL) to afford product (15 mg, 21%) as a yellow powder that had the following properties: mp: 295-297° C.; LC/MS (ESI+): 520 (M+H); 1H-NMR (DMSO-d6, 400 MHz): δ 11.20 (s, 1H), 9.45 (s, 1H), 8.42 (d, J=8.0, 1H), 8.28 (s, 1H), 8.15 (s, 1H), 7.65 (m, 2H), 7.52 (d, J=8.9, 1H), 7.30 (s, 1H), 7.20 (d, J=8.6, 1H), 7.05 (d, J=9.4, 1H), 3.20 (s, 3H), 3.18 (m, 4H), 2.65-2.20 (series of m, 6H), 1.65 (m, 4H), 1.55 (m, 2H).
