Procedure

A mixture of 2.3 g N,N',N"-trichloromelamine, 20 ml carbon tetrachloride, 8.46 g 4-chlorobutyryl chloride and 30 mg N,N-dimethylaminopyridine was placed in a 100 ml flask fitted with a magnetic stirring bar, a reflux condenser and argon inlet. The reaction mixture was slowly heated in an oil bath to about 60° C. and was stirred at about 60° C. for 5 hours. It was allowed to cool down to room temperature and then diluted with 50 ml hexanes. The contents were stirred at room temperature for 30 minutes and then filtered. The residue was washed with hexane and dried under reduced pressure. It was characterized to be N,N',N"-tris(4-chlorobutyryl)melamine on the basis of NMR and mass spectroscopy (4.2 g; 95% yield):
