| Abstract: | 4‐Aminomorpholine, 1‐aminopiperidine, and 1,1‐dimethylhydrazine were carried out in the corresponding methyl dithiocarbamates and those in turn in aminohydrazinethioamides, which under the influence of acid chlorides (benzoyl, 4‐chlorobenzoyl, 4‐fluorobenzoyl, 4‐methoxybenzoyl and 2‐furoyl) gave arylcarbonyl derivatives. Those compounds were cyclized in concentrated H2SO4 to 2‐(N‐cycloalkylamino‐ and N‐dimethylamino)‐amino‐5‐phenyl‐1,3,4‐thiadiazole derivatives and in 10% NaOH aqueous solution to 4‐cycloalkylamino‐ and 4‐dimethylamino‐3‐phenyl‐1,2,4‐triazole‐5(4H)‐thiones. |
