Reaction Steps
4-[1-dimethylamino-eth-(Z)-ylidene]-2-methyl-4H-oxazole-5-one (compound 15, 7.54 g, 44.8 mmol) was dissolved in ethanol (50 mL) and sodium hydride (179 mg, 4.5 mmol, 60% dispersion in mineral oil) wad added at room temperature. The solution was refluxed for 1 hr. The solvent was evaporated and the crude product was used without any further purification for the next step.
