Abstract

Hydrogenation of a mixture of ortho- and para-dinitro derivatives of 1,4-dimethoxybenzene in ethyl acetate under palladium catalysis, allows 3,6-dimethoxybenzene-l,2-diamine to be isolated as the sole product; this diamine is then converted into 4,7-dimethoxy-2-methyl-1H-benzimidazole, a building block for the preparation ofimidazobenzo(hydro)quinones.
