Procedure

10-Camphorsulfonic acid (70.5 mg, 0.303 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 (2,5-Dichloro-pyrimidin-4-yl)-(2-methoxy-4-morpholin-4-yl-phenyl)-amine (98 mg, 0.28 mmol) in Isopropyl alcohol (2 mL). The mixture was irradiated in a CEM microwave (140° C., 30 min). MP-Carbonate (2.69 mmol/g loading; 0.21 g, 0.57 mmol) and DCM (2 mL) were added and the mixture stirred for 1 h, then filtered onto a 5 g SiO2 cartridge, which which was air dried. The sample was chromatographed (ISCO, 2×12 g SiO2, 0-50% EtOAc:Hex) to afford 5-Chloro-N*2*-(9-ethyl-2-fluoro-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-3-yl)-N*4*-(2-methoxy-4-morpholin-4-yl-phenyl)-pyrimidine-2,4-diamine as a lavender film (43 mg, 29%). LCMS 529 (M+H), 1H-NMR (CDCl3): 8.23 (d, 1H, J=8.7 Hz), 8.00 (s, 1H), 7.77 (d, 1H, J=8.7 Hz), 7.58 (s, 1H), 6.75 (s, 1H), 6.60 (d, 1H, J=13.2 Hz), 6.55 (m, 2H), 4.08 (t, 2H, J=5.6 Hz), 3.91 (s, 3H), 3.88 (t, 4H, J=4.6 Hz), 3.17 (m, 8H), 1.98 (m, 2H), 1.21 (t, 3H, J=7.0 Hz); 19F-NMR: −135.
