Procedure
tert-Butyl 3-cyclohexyl-2-hydroxyimino-3-oxopropionate (2.6 g) and benzylamine (2.1 g) were dissolved in benzene (50 ml), and the mixture was refluxed under heating for 16 hr. The solvent was concentrated under reduced pressure. The obtained residue was purified by silica gel chromatography (chloroform:ethyl acetate=8:1) to give tert-butyl 5-cyclohexyl-2-phenylimidazole-4-carboxylate (0.90 g), melting point 222-223° C.
