Condensation of pyruvic aldehyde dimethyl acetal (I) with dimethylformamide dimehylacetal provided ketoenamine (II). This was cyclized with guanidine to afford aminopyrimidine (III). Then, hydrolysis of the dimethyl acetal of (III) with 3 M HCl yielded aldehyde (IV). 4-Fluorobenzaldehyde (V) was condensed with thiocresol (VI) and formamide in refluxing toluene to give 4-fluorophenyl-tolylthiomethyl formamide (VII), which was dehydrated to isocyanide (VIII) with POCl3 and Et3N at -30 C. Finally, imine (X), (obtained from pyrimidine aldehyde (IV) and 4-(3-aminopropyl)morpholine (IX)), was condensed with isocyanide (VIII) in the presence of 1,5,7-triazabicyclo[4.4.0]dec-5-ene to furnish the title imidazole.
