実験手順
This compound was prepared according to a procedure similar to that described in Procedure E. In a solution of 9-Bromo-4,5-dihydro-6-oxa-1,3a-diaza-benzo[e]azulene-2-carboxylic acid amide (200 mg, 0.64 mmol) in acetonitrile (3 mL) and triethylamine (3 mL) were added, Pd(PPh3)2Cl2 (44 mg, 0.06 mmol), 3-Ethynyl-1-methyl-pyrrolidin-3-ol (160 mg, 1.3 mmol) and CuI (12 mg, 0.06 mmol). Then the solution was bubbled N2 for 5 min and heated by microwave for 1 h at 100° C. under nitrogen. The reaction mixture was filtered and the filtrate was purified by column to afford crude product. The crude product was purified by Prep HPLC to afford the titled compound (22.3 mg, 10%). 1H NMR (DMSO-d6, 400 MHz): δ 8.52 (d, J=2.0 Hz, 1H), 8.18 (s, 1H), 7.79 (s, 1H), 7.56 (s, 1H), 7.32 (d, J=8.8 Hz, 1H), 7.15 (s, 1H), 7.03 (d, J=8.4 Hz, 1H), 4.48 (s, 4H), 2.95 (m, 1H), 2.77 (m, 2H), 2.67 (m, 1H), 2.31 (s, 3H), 2.28 (m, 1H), 2.08 (m, 1H). LCMS=353.1 [M+H]+.
