2-Hydroxy-6,7-dimethyl-naphtalene is sulfonated to 2-Hydroxy-6,7-dimethyl-naphtalene 3-sulfonic acid at 100°. On fusion of this sulfonic acid with potassium hydroxide 2,3-Dihydroxy-6,7-dimethylnaphtalene is obtained. The structure of this compound was proved by nuclear magnetic resonance spectroscopy. The latter compound is a good starting material for the synthesis of 6′,7′-Dimethylnaphto- (2′,3′) -imidazole-4,5 the base of a new vitamin B12-analogue, which was biosynthetically prepared recently.
