Studies on Heterocyclic Enaminonitriles. III. Reactions of 2-Benzamido-3-cyano-4,5-dihydrothiophenes with Amines

The reaction of 2-benzamido-3-cyano-4,5-dihydrothiophene (I) with cyclohexyllamine gave 4-cyclohexylamino-2-phenyl-5,6-dihydrothienopyrimidine (IVa) in 93percent yield.Similarly, I reacted with morpholine, piperidine and pyrrolidine to yield the co
