Abstract
The attempted ring-closure of thoxycarbonyl)hydrazinomethylenecarbonyl ]imidazole (5b) in sodium hydride/dimethyl sulfoxide at 50-60 degrees C afforded 1, 7-dibenzylxanthine (6) instead of the anticipated 5:8-fu sed heterocycle 4b. A tentative reaction pathway has been proposed for the observed transformation.
