A simple and direct procedure was developed for the synthesis of a novel series of polyfunctionalized pyrimidines. They were prepared via reaction of N-(substituted carbamothioyl)benzimidamides (prepared from the reaction of benzimidamide hydrochloride an

A simple and practical method for the one-pot synthesis of 3-aryl-5-amino-1,2,4-thiadiazoles from imidates and thioureas has been developed. The protocol proceeds through sequential base-mediated nucleophilic addition-elimination reactions and an I2-mediated oxidative coupling for the N–S bond formation. The approach employes readily available and nontoxic substrates and a simple workup to provide 3-aryl-5-amino-1,2,4-thiadiazoles that have a free or substituted amino group.
