Into an 8 ml sealed tube was placed 2-Amino-6,7-dihydro-9H-5-oxa-9-aza-benzocyclohepten-8-one (0.080 g, 0.45 mmol), 2-(2,5-Dichloro-pyrimidin-4-ylamino)-3-fluoro-N-methyl-benzamide (0.16 g, 0.49 mmol), and 10-Camphorsulfonic acid (0.11 g, 0.49 mmol). Isopropyl alcohol (2 mL, 0.03 mol) was added. The reaction was microwaved at 120° C. for 40 minutes, diluted with CH2Cl2, washed with aqueous sat'd NaHCO3, dried over MgSO4, filtered, and concentrated under reduced pressure. The reaction mixture was purified by silica gel chromatography (ISCO amine column 0-100% EtOAc in hexanes) to afford title compound as a yellow solid. LCMS: 457.17 (M+H), HPLC: 95% purity, 1H-NMR (CDCl3, 400 MHz) δ 8.78 (s, 1H), 8.05 (d, J=1.8 Hz, 1H), 7.80 (s, 1H), 7.45-7.40 (m, 3H), 7.35-7.31 (m, 2H), 6.90 (d, J=8.6 Hz, 1H), 6.79 (d, J=8.8 Hz, 1H), 6.43 (bd, 4.0 Hz, 1H), 4.42 (t, J=5.8 Hz, 2H), 2.94 (d, J=4.8 Hz, 3H), 2.81 (t, J=5.6 Hz, 2H).
