Reaction Steps

A mixture of 2-n-butyl-1-(2-chlorophenyl)methyl-1H-imidazol-5-carboxaldehyde (554 mg, 2 mmol), phenylacetic acid (310 mg, 2.3 mmol), potassium carbonate (126 mg, 0.91 mmol), and acetic anhydride (1 mL) was heated gradually to 140° C. and held at this temperature for 6 hours. The cooled reaction was diluted with water and the oily solid was separated, triturated several times with ether, and the solid was crystallized several times from methanol/ethyl acetate to give 143 mg (18%) of the title compound; mp 210°-212° C. The NMR was consistent with the trans olefinic product.
