Abstract

A new procedure for obtaining benzoxazoles characterized in that it starts from the general formula ** in which r1 r2 r3 and r4 are each chosen from the hydrogen alkogens and the alkylonitro sulfonodialkylamine groups by pumping 2 of these substituents of r belong to the same aromatic or cyclic cycle; process characterized in that an orot-aminophenol is reacted by heat with an orthoformic ester.
