Reaction Steps

N-s-Butyl-butyramide (0.99 g, 0.0069 m) in dry dioxan (10 ml) was cooled to 10° C. under nitrogen during the dropwise addition of a 1.445 M solution of n-butyl lithium (4.8 ml, 0.0069 m). The mixture was stirred for 15 minutes at 10° C. and then 4-methyl-2-methylsulphinyloxazole (1.0 g, 0.0068 m) in dry dioxan (10 ml) was added and the mixture allowed to warm to room temperature. It was stirred for 3 hours and then hydrolysed with water. The solvent was removed in vacuo and the ether extract of the residue was chromatographed on silica using ether. The resulting compound (title product) was distilled in vacuo as a colourless oil 0.95 g, b.p. 75°-76° C./0.5 mm.
