実験手順
Ethyl 2-hydroxyimino-3-(4-fluorophenyl)-3-oxopropionate (10.0 g) and 1-aminomethylnaphthalene (8.3 g) were reacted and treated in the same manner as in Starting Material Synthetic Example 1 to give ethyl 5-(4-fluorophenyl)-2-(1-naphthyl)imidazole-4-carboxylate (3.3 g). 3.0 g therefrom was dissolved in ethyl alcohol (100 ml) and 1 M sodium hydroxide solution (20 ml) was added. The mixture was reacted and treated in the same manner as in Starting Material Synthetic Example 2 to give 5-(4-fluorophenyl)-2-(1-naphthyl)imidazole-4-carboxyic acid (2.4 g), melting point 175° C. (decomposition).
