Reaction Steps
N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-N-ethyl-methanesulfonamide (99 mg, 0.27 mmol) in Isopropyl alcohol (4 mL) was added to 10-Camphorsulfonic acid (12 mg, 0.052 mmol) and 7-Amino-5,5-dimethyl-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (56 mg, 0.27 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 onto Celite. Chromatography (ISCO, 12 g silica gel, 40-80% EtOAc:Hex) afforded 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-ethyl-methanesulfonamide as an off white foam (78 mg, 54%). LCMS: 535 (M+H); 1H-NMR, CDCl3: 7.91 (s, 1H), 7.74 (d, 1H, J=8.5 Hz), 7.34 (s, 1H), 7.25 (s, 1H), 7.00 (s, 1H), 6.88 (d, 1H J=8.5 Hz), 6.02 (d, 1H, J=8.2 Hz), 3.99 (m, 1H), 3.75 (m, 1H), 3.30 (m, 1H), 3.20 (m, 1H), 2.92 (s, 3H), 2.45 (m, 1H), 2.40 (t, 2H, J=7.0 Hz), 2.13 (t, 2H, J=7.0 Hz), 1.95 (m, 2H), 1.44 (s, 6H), 1.39 (m, 3H), 1.16 (t, 3H, J=7.0 Hz).
