Procedure

To a solution of example 119 (0.060 g, 0.135 mmol) in dichloromethane (1 ml), 3-chloroperbenzoic acid (0.46 g, 0.270 mmol) was added and stirred at RT for 12 h. The mixture was diluted with water, extracted with dichloromethane, the organic layer dried over sodium sulphate and concentrated. The crude product was purified by column chromatography with methanol:dichloromethane as the eluent to afford the title compound as a grey solid. (0.016 g, 26%). M.P.: 212-215° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): 8.71 (d, J=8.8 Hz, 1H), 8.68 (d, J=9.1 Hz, 1H), 8.56 (m, 2H), 8.30 (d, J=1.5 Hz, 1H), 8.24 (m, 2H), 8.12 (s, 1H), 7.93 (d, J=8.6 Hz, 1H), 7.86 (dd, J=9.1, 1.8 Hz, 1H), 7.57 (d, J=8.0 Hz, 1H), 7.48 (dd, J=8.4, 6.0 Hz, 1H), 6.20 (s, 2H), 3.28 (m, 2H), 1.14 (t, J=7.3 Hz, 3H).
