Procedure
1,3-Dihydro-4-[4-(1H-imidazol-1-yl)benzoyl]-5-methyl-2H-imidazol-2-one (5.85 g, 21.8 mmol) (Example I) is combined in a pressure tube containing a magnetic stir bar with 37% aqueous formaldehyde (300 mL) and the mixture heated with stirring at 120° C. for 18 hr. The mixture is cooled, the tube opened and the solution evaporated in vacuo. Chromatography of the residue on silica gel affords the title compound.
