Participants

Reaction Steps

(4-Methyl-1-thiophen-3-yl-pentylideneaminooxy)-acetic acid (2.17 g, 8.5 mmol) was added to a 0.1 M sodium hydroxide solution (93.5 ml) and heated to reflux. A solution of potassium persulfate (3.45 g, 12.75 mmol) in water (10 ml) was added dropwise and heating continued. After 2 hours, the reaction mixture was extracted with dry diethyl ether (100 ml). The organic layer was then washed with saturate sodium bicarbonate, water and brine, dried (Na2SO4) and concentrated in vacuo. The resulting oil was purified by silica gel chromatography to afford the title compound as a colourless oil (196 mg, 13%). MS (ES+) 18. δH (d6DMSO): 1.42 (6H, s), 2.03 (2H, t), 2.60 (2H, t), 7.22 (1H, d), 7.42 (1H, d).
