十二种4-取代的2-硝基-(二烴胺基乙酰)苯胺(Ⅰa-1)在稀醋酸中以次硫酸鈉处理,一步“还原环化”成相应的5-取代的2-二煙胺甲基苯并咪唑(Ⅱa-1).

Twelve 5-substituted-2-dialkylaminomethyl benzimidazoles(Ⅱa-1) have been synthesized by "reductive cyclization" of the corresponding 4-bromo-,chloro-and methoxy-2-nitro-dialkylaminoacetanilides(Ⅰa-1) with sodium hyposulphite in dilute acetic acid.
