Participants

Reaction Steps

10-Camphorsulfonic acid (70 mg, 0.30 mmol) was added to 9-Ethyl-2-fluoro-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-3-ylamine (58 mg, 0.28 mmol) and N-[(1R,2R)-2-(2,5-Dichloro-pyrimidin-4-ylamino)-cyclohexyl]-methanesulfonamide (94 mg, 0.28 mmol) in Isopropyl alcohol (1 mL). The mixture was irradiated in a CEM microwave (140° C., min). MP-Carbonate (2.69 mmol/g loading; 0.22 g, 0.5793156293 mmol) and DCM (2 mL) were added and the mixture stirred for 1 h, then filtered onto a 5 g SiO2 cartridge, which was air dried. The sample was chromatographed (ISCO, 2×12 g SiO2, 0-50% EtOAc:Hex) to afford N-{(1R,2R)-2-[5-Chloro-2-(9-ethyl-2-fluoro-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-3-ylamino)-pyrimidin-4-ylamino]-cyclohexyl}-methanesulfonamide as a purple film (40 mg, 30%). LCMS 513 (M+H), 1H-NMR (CDCl3): 7.92 (s, 1H), 7.76 (d, 1H, J=8.4 Hz), 6.76 (s, 1H), 6.62 (d, 1H, J=13.3 Hz), 5.39 (d, 1H, J=7.4 Hz), 5.11 (d, 1H, J=7.1 Hz), 4.09 (t, 2H, J=6.0 Hz), 3.93 (m, 1H), 3.25 (m, 5H), 2.81 (s, 3H), 2.20 (m, 2H), 2.00 (m, 2H), 1.82 (m, 2H), 1.43 (m, 4H), 1.20 (t, 3H, J=7.0 Hz). 19F-NMR: −135.
