Procedure

To a solution of example 155 (0.056 g, 0.145 mmol) in DMF (0.5 ml) N-ethyldiisopropylamine (0.018 g, 0.145 mmol) and HATU (0.055 g, 0.145 mmol) were added and stirred for 5 min. Pyrrolidine (0.020 g, 0.290 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 a yellow solid (0.010 g, 16%). M.P.: 136-138° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): 8.87 (dd, J=2.7 Hz, 1H), 8.52 (d, J=8.7 Hz, 1H), 8.45 (s, 1H), 8.37 (d, J=7.7 Hz, 1H), 8.20 (s, 1H), 8.01 (d, J=8.6 Hz, 1H), 7.99 (s, 1H), 7.83 (m, 2H), 7.52 (dd, J=8.3, 4.2 Hz, 1H), 6.11 (s, 2H), 5.11 (s, 2H), 3.52 (t, J=6.7 Hz, 2H), 3.33 (m, 2H), 1.93-1.77 (m, 4H).
