Reaction Steps

A mixture containing ethyl 4-[4-[(4-dimethylaminopyrid-3-yl)methoxy]phenoxy]butanoate (25 mg), aqueous sodium hydroxide (1M, 0.2 ml), methanol (0.5 ml) and water (0.5 ml) was stirred for 3 hours then neutralised with hydrochloric acid (1M, 0.2 ml) and concentrated. The residue was dissolved in dichloromethane (5 ml), filtered, and the filtrate was concentrated to give the title compound (17 mg) as a colourless gum. NMR (d6DMSO+d4AcOH): δ2.0(2H,q); 2.4(2H,t); 3.35(6H,s); 3.95(2H,t); 5.1(2H,s); 6.8-7.0(4H, dd +1H,m); 8.15(1H,dd); 8.3(1H,d); m/e 331(M+H)+.
