Procedure

As shown in Scheme 1, a suitable nitro-uracil precursor, (1), is mixed with an appropriate aldehyde, (2), and piperidine, in a suitable solvent such as ethanol. The solution is heated to reflux for approximately 10-20 hours. After reflux, the mixture is concentrated and purified using conventional methods, such as thin layer chromatography, to produce the vinyl-nitro-uracil (3).
