Abstract Arylation of furan-2-carboxylic acid or its methyl ester with arenediazonium chlorides in the presence of copper (II) chloride gave the corresponding 5-arylfuran-2- carboxylic acids or methyl 5-arylfuran-2-carboxylates. 5-Arylfuran-2-carbonyl chlorides reacted with potassium thiocyanate and then with 5-methyl-1, 2-oxazol-3-amine to give 5- aryl-N-[3-(2-oxopropyl)-1, 2, 4-thiadiazol-5-yl] furan-2-carboxamides as a result of ...
