Versuchsvorschrift
A solution of 5-anilino-2-ethyl-1,3-benzoxazole-4,7-dione (1 eq.) in acetic acid is treated with N-chlorosuccinimide (1.1 eq.) at ambient temperature. The reaction medium is maintained under stirring for 2 hours before being concentrated, followed by taking up in ethanol and concentrating again. The residue is purified by medium pressure chromatography on silica in order to produce a violet-coloured powder.
