摘要

Abstract Treatment of 6-amino-5-arylazo-1, 3-dimethyluracils with ethyl propiolate gave the corresponding Michael-type adducts, 5-arylazo-1, 3-dimethyl-6- ethoxycarbonylvinylaminouracils, which on treatment with a mixture of hydrochloric acid and acetic acid caused the acid-catalyzed rearrangement accompanied with rearrangement to give rise to the corresponding 8-anilinomethyltheophylline derivatives.
