Procedure

To a solution of example 8 (0.200 g, 0.524 mmol) in DMF (1 ml) HOBT (0.084 g, 0.629 mmol), EDC-HCl (0.250 g, 1.31 mmol) and methylamine (0.2 ml, 1.57 mmol) were added and stirred for 5 min, 4-Aminotetrahydropyran (0.106 g, 1.04 mmol) was added at RT and the reaction mixture was stirred for 12 h. To the reaction mixture water was added and extracted with ethyl acetate, 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 an off-white solid (0.050 g, 20%.). M.P.: 202-205° C., 1H-NMR (δ ppm, DMSO-d6, 400 MHz): 8.88 (dd, J=4.1, 1.6 Hz, 1H), 8.69 (d, J=8.8 Hz, 1H), 8.44 (d, J=7.5 Hz, 1H), 8.38 (d, J=7.7 Hz, 1H), 8.33 (d, J=8.5 Hz, 2H), 8.20 (d, J=8.8 Hz, 1H), 8.03-7.99 (m, 4H), 7.85 (dd, J=8.7, 1.9 Hz, 1H), 7.53 (dd, J=8.3, 4.2 Hz, 1H), 6.22 (s, 2H), 4.04 (m, 1H), 3.89 (d, J=9.7 Hz, 2H), 3.39 (t, J=10.0 Hz. 2H), 1.78 (d, J=10.5 Hz, 2H), 1.63 (m, 2H).
