Procedure
1-Trifluoroacetylimidazole (10 g) was added dropwise to 4-methyl-2-trimethylsilyloxazole (J. Chem. Soc., Chem. Commun., 1984, 258) (9.95 g) in diethyl ether (100 ml) at 0° C. under an atmosphere of dry nitrogen. The mixture was stirred overnight at room temperature. Water was added and the organic layer was separated, washed, dried and evaporated. Flash chromatography gave the title compound.
