Methyl iodide → HCID 54671268, compound

Participants

Reaction Steps

Sodium hydride (0.010 g, 0.259 mmol) was added at 0° C. to a solution of example 16 (0.100 g, 0.259 mmol) in DMF (1 ml) and stirred for 30 min. Methyl iodide (0.073 g, 0.518 mmol) was added and the reaction mixture was warmed to RT. After 12 h, the reaction mixture was poured into ice-cold water and extracted with ethyl acetate, washed with brine, dried over sodium sulphate and concentrated. The crude product was purified by column chromatography with methanol:dichloromethane to afford the title compound as an off-white solid (0.033 g, 32%). M.P.: 200-201° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): 8.88 (dd, J=4.2, 1.7 Hz, 1H), 8.68 (d, J=8.8 Hz, 1H), 8.37 (d, J=8.4 Hz, 1H), 8.18 (d, J=8.8 Hz, 1H), 8.11-8.00 (m, 4H), 7.83 (dd, J=8.7, 1.9 Hz, 1H), 7.61 (t, J=7.7 Hz, 1H), 7.53 (dd, J=8.4, 4.2 Hz, 1H), 6.22 (s, 2H), 4.53 (s, 2H), 3.33 (s, 3H).
