Procedure

The compound 2,4-dichloro-6-nitroazidobenzene is dissolved in glacial acetic acid then refluxed for several hours to yield 4,6-dichlorobenzofuroxan. This step is similar to that described in Boulton et al., J. Chem. Soc. B., p. 909 (1967) except that the present invention uses a longer reflux time.
