2-Aminopyridines, with a variety of polar 6-substituents, were elaborated by displacement of a methylsulfinyl group from the 6-position of the pyridine ring. The requisite 6-thiomethyl pyridines were synthesized by reaction of 2-(1-phenylethylidene)propanedinitriles with dimethyl N-cyanodithioiminocarbonate.
具有各种极性6-取代基的2-氨基吡啶是通过从吡啶环的6-位上取代一个甲亚磺酰基而制得的。所需的6-硫代甲基吡啶是通过2-(1-苯基亚乙基)丙二腈与二甲基N-氰基二硫代亚氨基碳酸酯反应合成的。
