Abstract: The synthesis of furo[3,2-e]pyrimidine-4-thione is described starting from 5-methoxy-2-furylisocyanate. The starting material is converted to substituted ureas by reaction with secondary amines. Chlorination of a urea affords chloroformamidine, which in turn cyclizes with potassium thiocyanate to give the target furopyrimidinethione.
