Reaction Steps
1-(dimethylsulphamoyl)-2-(hydroxyiminomethyl)-4-phenylimidazole, m.p 165°-170° (dec.). A slurry of this product (0.882 g) in dry tetrahydrofuran (20 ml) was added to sodium hydride (90 mg of 80g suspension in oil) in dry tetrahydrofuran. After 1.5 hours at room temperature ethyl chloroformate (0.285 ml) was added and the mixture stirred overnight. The mixture was then added to ethyl acetate and worked up in conventional manner to give a viscous oil. This was purified by flash column chromatography to give 2-cyano-1-ethoxycarbonyl-3-phenylimidazole, m.p. 109°-111°. (Compound 3)
