Reaction Steps

A microwave vessel was charged with 2-(2,5-dichloro-pyrimidin-4-ylamino)-5-morpholin-4-yl-benzamide (50.0 mg, 0.136 mmol), 7-amino-1-methyl-1,3,4,5-tetrahydro-1-benzazepin-2-one (31.6 mg, 0.166 mmol), 10-camphorsulfonic acid (3.5 mg, 0.015 mmol) and isopropyl alcohol (2 mL). This mixture was heated at 120° C. for 20 minutes in a microwave reactor (sealed vessel). 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 as a yellow powder (49.5 mg, 70%) that had the following properties: mp: 288-290° C.; LC/MS (ESI+): 522 (M+H); 1H-NMR (DMSO-d6, 400 MHz): δ 11.29 (s, 1H), 9.45 (s, 1H), 8.46 (d, J=8.0, 1H), 8.28 (s, 1H), 8.16 (s, 1H), 7.69 (s, 1H), 7.64 (s, 1H), 7.52 (d, J=8.9, 1H), 7.32 (s, 1H), 7.20 (d, J=8.6, 1H), 7.09 (d, J=9.4, 1H), 3.77 (m, 4H), 3.25 (s, 3H), 3.15 (m, 4H), 2.60 (m, 2H), 2.20-2.10 (m, 2H), 2.10-2.00 (m, 2H).
