Procedure

N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-N-methyl-methanesulfonamide (95 mg, 0.27 mmol) in Isopropyl alcohol (4 mL) was added to 7-Amino-5,5-dimethyl-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (56 mg, 0.27 mmol) and 10-Camphorsulfonic acid (64 mg, 0.28 mmol) and was heated in a Microwave vial for 90 min 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. The material was taken up in DCM and was chromatographed (ISCO, 12 g silica gel, 50% EtOAc/Hex-non-retained) to afford the N-{(1R,2R)-2-[5-Chloro-2-(5,5-dimethyl-2-oxo-2,3,4,5-tetrahydro-1H-benzo[b]azepin-7-ylamino)-pyrimidin-4-ylamino]-cyclohexyl}-N-methyl-methanesulfonamide as off white solids (145 mg, 100%). mp=140-145° C.; LCMS: 521 (M+H); 1H-NMR, CDCl3: 7.92 (s, 1H), 7.68 (d, 1H, J=8.5 Hz), 7.46 (s, 1H), 7.39 (s, 1H), 7.11 (s, 1H), 6.89 (d, 1H, J=8.5 Hz), 5.69 (d, 1H, 7.8 Hz), 4.07 (m, 1H), 3.77 (m, 1H), 2.85 (s, 3H), 2.75 (s, 3H), 2.41 (t, 2H, J=7.0 Hz), 2.13 (m, 2H, J=7.0 Hz), 1.90 (m, 4H), 1.44 (s, 6H), 1.37 (m, 4H).
