A stirred mixture of 4,4'(hexamethylenediimino)bis(2,2,6,6-tetramethylpiperidine) (6.36 grams; 0.0161 mole), 2-chloro-4,6-bis(t-octylamino)-1,3,5-triazine (9.56 grams; 0.0322 mole), and powdered sodium hydroxide (1.29 grams; 0.0322 mole) in xylene (75 mls) is stirred and heated at reflux while removing water therein by means of a water trap. The reaction mixture is stirred and heated at reflux for 18 hours, cooled to 25° C., and treated with acetonitrile (200 mls). The reaction mixture is filtered to recover a precipitate, and the solid is washed successively with water and acetone, and dried to obtain 10.0 grams of product which melts at 208°-209° C. after recrystallization from xylene.
