Reaction Steps
N-Methyl-acetamide (1.02 g, 0.0140 m) in HMPA (10 ml) was stirred at 50° C. under nitrogen during the portionwise addition of 50% potassium hydride/oil dispersion (1.12 g, 0.0140 m). After the addition, the mixture was warmed to 100° C. and 2-n-hexylsulphinyl-4-methyloxazole (3.0 g, 0.0139 m) in HMPA (10 ml) was added and the mixture stirred at 100° C. for 5 hours. The mixture was then hydrolysed with water, solvent removed in vacuo and the product isolated by column chromatography on silica using ether. Recrystallisation from diethyl ether/hexane at -20° C. gave the title product as colourless needles, m.p. 27°-29° C.
