Procedure

A mixture of 2-ethyl-1,3-benzoxazole-4,7-dione (1 eq) and aniline (1.1 eq.) in ethanol is kept under stirring for 1 hour. The reaction medium turns to dark violet. After concentration, the residue is purified by medium pressure chromatography on silica in order to produce a violet-coloured powder. Melting point: 200° C.
