tert-Butyl 2-hydroxyimino-3-oxo-3-(4-pyridyl)propionate (5.0 g) and 1-naphthylmethylamine (3.5 g) were dissolved in toluene (60 ml). The mixture was refluxed under heating for 3 hr while dehydrating with Dean-stark trap. After cooling, the precipitated crystals were collected by filtration and dried to give tert-butyl 2-(1-naphthyl)-5-(4-pyridyl)imidazole-4-carboxylate (1.3 g), melting point 184-190° C.
