실험 절차

A mixture of 15.8 g (0.1 mole) of 2-p-tolylimidazole, 24 ml (0.3 mole) of 37% formalin and 2 g of potassium hydroxide was heated for 30 minutes with stirring in the same way as in Example 1, and the reaction mixture was post-treated in the same way as in Example 1 except that methyl cellosolve was used instead of methanol as a recrystallization solvent to afford 2-p-tolyl-4,5-dihydroxymethyl imidazole as a final product in an amount of 2 g (yield 9%).
