Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 100-48-1, name is Isonicotinonitrile. A new synthetic method of this compound is introduced below., Recommanded Product: 100-48-1
General procedure: To a stirred mixture of nitrile (1.0 mmol) and thiosemicarbazide(1.1 mmol) was added trifluoroacetic acid (4 mL) and then themixture was refluxed for 6 h under stirring. After completion ofreaction cooled to room temperature and diluted with aqueousammonia. The precipitated solid was filtered off, washed with hotwater and dried in air. The product 14a-f were used in the next stepwithout further purification. Spectral data of compounds such as 5-phenyl-1,3,4-thiadiazol-2-amine (14a) [63], 5-(p-tolyl)-1,3,4-thiadiazol-2-amine (14b) [63], 5-(3,4,5-trimethoxyphenyl)-1,3,4-thiadiazol-2-amine (14c) [64], 5-(4-nitrophenyl)-1,3,4-thiadiazol-2-amine (14d) [63], 5-(pyridin-4-yl)-1,3,4-thiadiazol-2-amine(14e) [63] and 5-(thiophen-2-yl)-1,3,4-thiadiazol-2-amine (14f)[63] were agreement with literature report.
