Reaction Steps

2-Amino-5-methyl-8,9-dihydro-5H-7-oxa-5-aza-benzocyclohepten-6-one (0.0435 g, 0.000226 mol), (2,5-Dichloro-pyrimidin-4-yl)-{2-fluoro-6-[2-(tetrahydro-pyran-2-yloxy)-ethoxy]-phenyl}-amine (0.091 g, 0.00023 mol), 10-Camphorsulfonic acid (0.0788 g, 0.000339 mol), and Isopropyl alcohol (2 mL) were added to a 10 mL microwave tube and microwaved at 120° C. for 30 minutes. The reaction mixture was then purified by HPLC, lyophilized and neutralized with MP-carbonate to afford 2-{5-Chloro-4-[2-fluoro-6-(2-hydroxy-ethoxy)-phenylamino]-pyrimidin-2-ylamino}-5-methyl-8,9-dihydro-5H-7-oxa-5-aza-benzocyclohepten-6-one as a yellow solid (11 mg, 10%). MP=199-201° C.; LCMS: 474 (M+H); HNMR (CDCl3): 8.07 (s, 1H), 7.36 (m, 2H), 7.10 (m, 1H), 6.84 (m, 4H), 6.64 (s, 1H), 4.42 (t, J=7.04 Hz, 2H), 4.13 (m, 2H), 3.87 (m, 2H), 3.33 (s, 3H), 2.78 (t, J=6.32 Hz, 2H).
