Participants

Reaction Steps

N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-N-methyl-methanesulfonamide (95 mg, 0.27 mmol), 8-Methoxy-3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamine (67 mg, 0.27 mmol), and 10-Camphorsulfonic acid (96 mg, 0.41 mmol) in Isopropyl alcohol (4 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; 0.35 g, 0.941 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-[8-methoxy-3-(2-methoxy-ethyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ylamino]-pyrimidin-4-ylamino}-cyclohexyl)-N-methyl-methanesulfonamide as a off white foam (99 mg, 65%). LCMS: 567 (M+H); 1H-NMR, CDCl3: 8.17 (s, 1H), 7.91 (s, 1H), 7.35 (s, 1H), 6.64 (s, 1H), 5.56 (s, 1H), 4.10 (m, 1H), 3.87 (s, 3H), 3.7 (m, 3H), 3.35 (s, 3H), 2.9 (m, 6H), 2.83 (s, 3H), 2.74 (s, 3H), 2.4 (m, 1H), 1.9 (m, 4H), 1.65 (m, 3H), 1.35 (m, 4H).
