Procedure

To a solution of Example 57c (0.477 g, 0.930 mmoles) in DMF (5.3 ml), ethanol (2.6 ml) and water (2.6 ml), N-Boc-3-methyl-6-indazoleboronic acid pinacol ester 98 (0.500 g, 1.395 mmoles) and sodium carbonate (0.295 g, 3.318 mmoles) were added and the system is degassed for 30 min. Tetrakistriphenylphosphine Palladium (0.053 g, 0.046 mmoles) was added under nitrogen atmosphere and heated to 80° C. After 12 h, the reaction mixture was celite filtered, concentrated and extracted with ethyl acetate. The organic layer was dried over sodium sulphate and concentrated under reduced pressure. The crude product was purified by column chromatography with methanol: dichloromethane to afford the title compound as off-white solid (0.100 g, 20% yield). MP: 246-248° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): δ 12.75(s,1H), 8.22(s,1H), 8.06(dd, J=8.5,1.8 Hz, 1H), 7.84(d, J=8.3 Hz, 1H), 7.80(m,1H), 7.62(s,1H), 7.51(d, J=8.2 Hz, 2H), 7.39-7.31(m, 2H), 7.18(m, 2H), 7.12(dt, J=8.3,2.6 Hz, 1H), 5.56(s,2H), 2.51(s,3H). Mass: 517.51(M+).
