실험 절차

To a suspension of 1.88 g (0.01 mol) of 2-phenylimidazole-4-carboxylic acid in a mixture of 3 ml of ~37% formaldehyde and 3 ml of 1,4-dioxane is added 2.1 g (0.02 mol) of sodium carbonate, and the resultant mixture is heated at 60°-70° C. for 5 hours, with stirring. After completion of the reaction, 5 ml of water is added, and the mixture is allowed to stand for 2 hours, on cooling. The resultant solid is recovered by filtration and recrystallized from ethyl acetate and filtered to afford 2-phenyl-4-hydroxymethylimidazole as a solid, m.p.168°-170° C.
