[Bisbenzofuro[3,2-b: 2',3'-e]pyridines].
Heating the potassium 3-enaminobenzo[b]furan-2-carboxylate 3 in acetic acid on 110 degrees C yielded the pentacyclic acetate 6. The acetic acid 7, formed by hydrolysis of the ester 6, decarboxylated easily giving 6-methyl-bis[1]benzofuro[3,2-b: 2',3'-e]pyridine (8).
