One pot synthesis of 3-[2-(arylamino)thiazol-4-yl]coumarins in a three-component synthesis and a catalyst and solvent-free synthesis on grinding
An efficient synthesis of 3-[2-(arylamino)thiazol-4-yl]coumarins in excellent yields are described. Reaction of 3-(2-bromoacetyl)coumarin with potassium thiocyanate and arylamines, in alcohol resulted in the formation of title compounds in one pot. The sa
