A new procedure, which avoided the unstable pyrimidine aldehye (X), started by condensing pyruvic aldehyde (XIII) with aminopiperidine (XI). The resulting imine (XIV) was reacted with tosyl isonitrile (V) to form the acetyl imidazole (XV). Subsequent treatment of (XV) with N,N-dimethylformamide dimethyl acetal gave enaminoketone (XVI), which was then condensed with guanidine (VIII) to produce the required pyrimidine ring.
