Morpholine → HCID 58269171, compound

Participants

Reaction Steps

To a solution of Intermediate 3 (0.30 g, 0.761 mmoles) in THF (2 ml), was added morpholine (0.066 g, 0.761 mmoles) at RT and refluxed for 12 h. The reaction mixture was cooled, diluted with aqueous bicarbonate solution and extracted with ethyl acetate. The organic layer was dried over sodium sulphate and concentrated under reduced pressure. The crude product was purified by column chromatography with ethyl acetate: petroleum ether to afford the title compound as off-white solid (0.40 g, 79% yield). 1H-NMR (δ ppm, DMSO-D6, 400 MHz): δ 8.12(d, J=2.2 Hz, 1H), 7.98(dd, J=8.8,2.3 Hz, 1H), 7.72 (d, J=8.9 Hz, 1H), 7.45-7.39(m, 3H), 7.29(d, J=7.0 Hz, 2H), 3.50(t, J=4.2 Hz, 4H), 3.40(s, 2H), 2.32(br S, 4H).
