Abstract
1,248,514. 3 - Mercapto - 1,2,4 - triazoles. FUJI PHOTO FILM CO. Ltd. 15 July, 1969 [15 July, 1968], No. 35637/69. Heading C2C. [Also in Division G2] 5 - Ethyl - 4 - phenyl - 3 - mercapto - 1,2,4- triazole is prepared by dissolving 4-phenylthiosemicarbazide in cooled pyridine and adding propionyl chloride. Similarly 5-n-pentyl-4:-phenyl-3-mercapto-1,2,4-triazole is prepared using 4-phenylthiosemicarbazide and caproyl chloride, 4,5 - diethyl - 3 - mercapto - 1,2,4 - triazole is prepared using 4-ethylthiosemicarbazide and propionyl chloride and 4-ethyl-5-phenyl-3-mercapto-1,2,4-triazole is prepared using 4-ethylthiosemicarbazide and benzoyl chloride. 5-(paminophenyl) - 4 - ethyl - 3 - mercapto - 1,2,4- triazole is prepared by dissolving p-acetamidobenzoylhydrazine in ethanol, adding ethyl thioisocyanate and refluxing. Other 3-mercapto- 1,2,4-triazoles of the general formula where R 1 and R 2 are alkyl or optionally substituted, including carbonamido substituted, phenyl are also disclosed.
