EXAMPLE - 1,2-Dichlorobenzene (600 ml) was added to 4-amino-2,2,6,6-tetramethylpiperidine (125 g) and then cyanuric chloride (36.9 g) was added and the reaction mixture was stirred for 30 minutes. The reaction mixture was worked up to give N,N',N"-tris-(2,2,6,6-tetramethyl-piperidin-4-yl)-1,3,5-triazine-2,4,6-triamine. Dichloromethane (400 ml), water (150 ml), sodium bicarbonate (113.4 g) and N,N',N"-Tris-(2,2,6,6-tetramethyl-piperidin-4-yl)-1,3,5-triazine-2,4,6-triamine (81.6 g) were added. Peracetic acid (137 g, as 40% solution in acetic acid) was then added to the reaction mixture keeping the temperature of 25-32 degrees C. Water (150 ml) and dichloromethane (100 ml) were added and the reaction mixture was stirred 15 hour. Peracetic acid (34 g, as 40% solution in acetic acid) was added and the reaction mixture was stirred 5 hour. The reaction mixture was worked up to give N,N',N"-tris-(2,2,6,6-tetramethyl-piperidin-4-yl-N-oxyl)-1,3,5-triazine-2,4,6-triamine.
