Procedure
A microwave vessel was charged with 3-chloro-2-(2,5-dichloro-pyrimidin-4-ylamino)-N-methyl-benzamide (50.00 mg, 0.1508 mmol), 7-amino-1-(2-methoxy-ethyl)-1,3,4,5-tetrahydro-1-benzazepin-2-one (39 mg, 0.16 mmol), 10-camphorsulfonic acid (6.0 mg, 0.026 mmol) and isopropyl alcohol (2 mL) and heated to at 120° C. for 70 minutes in a microwave reactor (sealed vessel). The reaction was diluted with water (10 mL) and saturated aqueous solution of NaHCO3 before extracting into DCM. The organic layer was dried by passing through a filter funnel loaded with MgSO4; the filtrate was evaporated onto celite prior to purification by chromatography (amine modified silica gel, 30% EtOAc/Hexane→80% EtOAc gradient). The appropriate fractions were combined, evaporated to afford a solid that was triturated with ether (2×2 mL) and yielded product (23.9 mg, 30%) as a white foam that had the following properties: m.p.=136-157° C., bubbled; LC/MS (ESI+): 529 (M+H); 1H-NMR (CDCl3, 400 MHz): δ 8.12 (s, 1H), 8.03 (s, 1H), 7.62 (d, J=8.0, 1H), 7.52 (d, J=8.0, 1H), 7.31 (dd, J=8.0, 7.8, 1H), 7.27 (m, 1H), 7.220 (d, J=8.6, 1H), 7.09 (d, J=8.6, 1H), 6.98 (s, 1H), 6.10, (s, 1H), 3.7-4.2 (m, 2H), 3.55-3.47 (m, 2H), 3.30 (s, 3H), 2.95 (d, J=4.9, 3H), 2.9-2.4 (m, 2H), 2.3-2.2 (m, 2H), 1.8-2.3 (m, 2H).
