Procedure

N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-N-methyl-methanesulfonamide (79 mg, 0.22 mmol), 7-Amino-1-ethyl-6-methoxy-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (52 mg, 0.22 mmol), and 10-Camphorsulfonic acid (80 mg, 0.34 mmol) in Isopropyl alcohol (3 mL) and was heated in a microwave vial for 2 h at 120° C. Upon cooling, the mixture was treated with MP-Carbonate (2.69 mmol/g loading; 0.29 g, 0.78 mmol) for 1 h, was filtered and was concentrated in vacuo. Chromatography (ISCO, 2×12 g silica gel, 0-80% EtOAc:Hex) afforded N-{(1R,2R)-2-[5-Chloro-2-(1-ethyl-6-methoxy-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-7-ylamino)-pyrimidin-4-ylamino]-cyclohexyl}-N-methyl-methanesulfonamide as a white foam (33 mg, 27%). LCMS: 551 (M+H), 1H-NMR (CDCl3): 8.35 (d, 1H, J=8.9 Hz), 7.94 (s, 1H), 7.35 (s, 1H), 6.96 (d, 1H, J=8.9 Hz), 5.72 (d, 1H, J=7.4 Hz), 4.06 (m, 1H), 3.82 (m, 4H), 3.5 (br s, 1H), 3.0 (br s, 1H), 2.85 (s, 3H), 2.78 (s, 3H), 2.47 (m, 1H), 2.29 (m, 2H), 1.84 (m, 3H), 1.71 (m, 1H), 1.25-1.5 (m, 6H), 1.13 (t, 3H, J=7.1 Hz).
