Methods for the synthesis of the esters of 1,4-dihydropyridine-3,5-dicarbothionic acids by the thionation of the carbonyl analogs with Lawesson's reagent are developed. The influence of the substituents at the nitrogen atom on the course of the thionation reaction is considered. The physicochemical
