Procedure

To a solution of example 8 (0.150 g, 0.393 mmol) in DMF (1 ml), HOBT (0.063 g, 0.471 mmol), EDC-HCl (0.187 g, 0.983 mmol) and triethylamine (0.16 ml, 1.17 mmol) were added and stirred for 5 min, (R)-pyrrolidin-3-ol (0.030 g, 0.353 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 amide as a yellow solid (0.015 g). The amide was dissolved in THF (2 ml), ether saturated with HCl (2 ml) was added at 0° C. and stirred for 15 min. The precipitate formed was washed with ether and dried under vacuum to afford the title compound as a yellow solid (0.017 g, 10%), M.P.: 120-122° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): 8.87 (d, J=2.9 Hz, 1H), 8.68 (d, J=8.7 Hz, 1H), 8.38 (d, J=8.2 Hz, 1H), 8.30 (d, J=8.2 Hz, 2H), 8.17 (d, J=8.8 Hz, 1H), 8.02 (d, J=8.3 Hz, 2H), 7.83 (d, J=8.7 Hz, 1H), 7.69 (m, 2H), 7.52 (dd, J=8.2, 4.1 Hz, 1H), 6.21 (s, 2H), 3.61 (m, 3H), 3.44 (m, 1H), 1.95-1.80 (m, 4H).
