Reaktionsschritte
N-Ethyl-acetamide (1.18 g, 0.0135 m) in dry dimethylformamide (10 ml) was stirred at room temperature under nitrogen during the portionwise addition of 50% sodium hydride/oil dispersion (0.65 g, 0.0135 m). After the addition, the mixture was warmed to 50° C. and then 4-methyl-2-phenylmethylsulphinyloxazole (3.0 g, 0.0135 m) was added. The mixture was stirred at 50° C. for 5 hours and then hydrolysed with water. The solvent was evaporated in vacuo and the residue extracted with diethyl ether. Column chromatography on silica using ether gave a pale yellow oil which gave the title product as a colourless oil on distillation, b.p. 50°-51° C./0.05 mm.
