Reaction of 4-Aryl-3-thiosemicarbazides with Phenylisothiocyanate: A Facile Synthesis of Thiazole, Pyrazole and Pyrimidine Derivatives
摘要:
AbstractThe reaction of 4‐aryl‐3‐thiosemicarbazides 1a‐d with phenylisothiocyanate gave the intermediate potasium salts 2a‐d. The latter afforded 3a‐d, 13a‐d and 19 upon the reaction with phenacyl bromide, monochloroacetic acid and ethyl bromocyanoacetate respectively.
