Bicyclo[2.2.1]heptane-1-methanesulfonic acid, 7,7-dimethyl-2-oxo-, (1S)- → 2-[2-(9-Acetyl-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-3-ylamino)-5-chloro-pyrimidin-4-ylamino]-3-fluoro-N-prop-2-ynyl-benzamide

Reaction Steps

1-(3-Amino-7,8-dihydro-6H-5-oxa-9-aza-benzocyclohepten-9-yl)-ethanone (97 mg, 0.47 mmol), 2-(2,5-Dichloro-pyrimidin-4-ylamino)-3-fluoro-N-prop-2-ynyl-benzamide (167 mg, 0.494 mmol), and 10-Camphorsulfonic acid (16 mg, 0.070 mmol) in Isopropyl alcohol (4 mL) was irradiated in a CEM microwave (120° C., 30 min). The mixture was neutralized with MP-carbonate (0.3 mmol) and purified on silica gel (ISCO, 2×12 g, 0-100% EtOAc:Hex) to afford 2-[2-(9-Acetyl-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocyclohepten-3-ylamino)-5-chloro-pyrimidin-4-ylamino]-3-fluoro-N-prop-2-ynyl-benzamide as a light brown foam (144 mg, 60%). MP=196-199° C.; LCMS: 509 (M+H); 1H-NMR (DMSO): 9.50 (s, 1H), 9.21 (s, 1H), 8.99 (m, 1H), 8.20 (s, 1H), 7.49 (m, 3H), 7.34 (s, 1H), 7.16 (m, 1H), 7.06 (m, 1H), 4.55 (m, 1H), 4.34 (m, 1H), 4.01 (d, 2H, J=2.3 Hz), 3.55 (m, 1H), 3.11 (t, 1H, J=2.3 Hz), 2.62 (m, 1H), 1.95 (m, 1H), 1.72 (m, 4H).
