Preparation of Stilbenyl Derivatives of 1,2,4‐Oxadiazoles Schiffs bases derived from 3‐ and 5‐( p ‐formylphenyl)‐phenyl‐1,2,4‐oxadiazoles and chloroanilines are reacted with various p ‐tolyl substituted aromatic heterocycles in the presence of dimethylformamide and potassium hydroxide to yield the corresponding heterocyclic substituted stilbenes (‘Anil synthesis’). The reactivity of 5‐[4‐(chlorophenylimino‐methyl)phenyl]‐3‐phenyl‐1,2,4‐oxadiazoles is very low and side reactions will predominate.
