Procedure

A mixture of (E)-3-[5-methyl-1-(triphenylmethyl)-1H-imidazol-4-yl]-1-(2-methyl-1-naphthalenyl)-2-propen-1-one (1.25 g), acetic acid (10 ml), THF (10 ml) and water (10 ml) was heated on a steam bath for 1 h. The mixture was then hydrogenated according to the General Procedure and the resulting filtrate was evaporated in vacuo and partitioned between dichloromethane (3×75 ml) and 0.2N sodium hydroxide (100 ml). The combined organic layers were dried and evaporated in vacuo to leave a foam (1.3 g) which was purified by FCC eluting with System A (94.5:5:0.5) to give the free base of the title compound as an oil. The product of maleic acid formation was triturated with ether to give the title compound (0.78 g), m.p. 108°-109°.
