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 20 .degree.C and 50 .degree.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 90 .degree. C and 100 .degree.C to convert the 3,3,5,6-tetrachloro-5,6-dihydropyridin-2-one to 3,3,5-trichloroglutarimide.
