Process for the preparation of 3,3,5-trichloroglutarimide

3,3,5-Trichloroglutarimide is prepared by combining 4-cyano-2,2,4-trichlorobutanoyl chloride with water in an inert organic solvent at a temperature between about 20 DEG C. and about 50 DEG C. to obtain a mixture of 3,3,5-trichloroglutarimide and 3,3,5,6-tetrachloro-5,6-dihydropyridin-2-one. The 3,3...

Summary:3,3,5-Trichloroglutarimide is prepared by combining 4-cyano-2,2,4-trichlorobutanoyl chloride with water in an inert organic solvent at a temperature between about 20 DEG C. and about 50 DEG C. to obtain a mixture of 3,3,5-trichloroglutarimide and 3,3,5,6-tetrachloro-5,6-dihydropyridin-2-one. The 3,3,5,6-tetrachloro-5,6-dihydropyridin-2-one is then heated in the presence of water and inert organic solvent to between about 90 DEG C. and about 100 DEG C. to convert the 3,3,5,6-tetrachloro-5,6-dihydropyridin-2-one to 3,3,5-trichloroglutarimide.
