Photochemical bromination of 7-methylcoumarin (I) using N-bromosuccinimide and azobis(isobutyronitrile) provided the benzylic bromide (II). N-Phenyl ethylenediamine (V) was prepared by reaction between aniline (III) and oxazolidone (IV) at 140 C. Then, alkylation of amine (V) with bromide (II) in the presence of K2CO3 in refluxing acetonitrile provided the title compound.
