실험 절차

A microwave vessel was charged with 8-amino-1-(2-methoxy-ethyl)-1,3,4,5-tetrahydro-1-benzazepin-2-one (51.3 mg, 0.219 mmol), 2-(2,5-dichloro-pyrimidin-4-ylamino)-3,N-dimethyl-benzamide (56.8 mg, 0.182 mmol), 10-camphorsulfonic acid (4.2 mg, 0.018 mmol) and isopropyl alcohol (2.0 mL) and heated at 120° C. for 60 minutes in a microwave reactor (sealed vessel). The reaction mixture was quenched with a slurry of saturated, aqueous NaHCO3 and stirred for 2 h. This mixture was diluted with water (10 mL) and extracted into DCM. The organic layer was dried by passing through a funnel filled with Na2SO4, and the filtrate was evaporated onto celite prior to purification by chromatography (amine modified silica gel, 25% 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 (50.0 mg, 54%) as a white powder that had the following properties: mp: 185-187° C.; LC/MS (ESI+): 509 (M+H); 1H-NMR (DMSO-d6, 400 MHz): δ 9.30-9.17 (m, 2H), 8.29 (br s, 1H), 8.13 (s, 1H), 7.45-7.38 (m, 2H), 7.35 (m, 1H), 7.30-7.18 (m, 2H), 6.92 (d, J=7.9, 1H), 4.05 (br s, 2H), 3.28 (br s, 2H), 3.09 (s, 3H), 2.70 (d, 3H, J=4.3), 2.55 (m, 2H) 2.25 (2, 3H), 2.20-1.80 (series of m, 4H).
