Procedure

The filtrate from the hydrogenation of 1-(5-fluoro-1-naphthalenyl)-3-(5-methyl-1H-imidazol-4-yl)-2-propen-1-one (1.01 g) was treated with maleic acid (418 mg) and the resultant solution was evaporated to dryness to give a solid. This was recrystallised from methanol/ethyl acetate to give the title compound (920 mg), m.p. 138°-140°.
