ABSTRACT:
A potassium salt useful in the production of N-substituted-1-alkylthio-2-nitroethenamines is produced by the reaction of the dipotassium salt of nitrodithioacetic acid with certain straight chain alkylamines, thereby converting only one of the KS-groups to an alkylamine group. The resulting monopotassium salt may be alkylated to produce the required N-substituted-1-alkylthio compound which may be reacted with a suitable amine to produce the histamine H.sub.2 -antagonist ranitidine.
