Procedure

To a suitably equipped 3-necked flask, are added 15.6 g (0.05 m) of bis(2-hydroxypropyl)(imino diethylene)bis carbamate dissolved in 50 g of n-butanol. To this solution are added slowly 9.2 g (0.05 m) of cyanuric chloride dissolved in 75 g of ethylacetate. The reaction mixture is allowed to stir at 0°-5° C. and progress of the reaction is monitored by tlc. After all the cyanuric chloride is reacted to the mono substituted product, 8.4 g of sodium bicarbonate and 3.65 g (0.05 m) of n-butylamine are added. The reaction temperature is raised to 35°-45° C. and maintained there until most of the n-butylamine has reacted. At this point 4.7 g (0.05 m) aniline are added and the reaction temperature raised to 115° C. after distilling out ethyl acetate. After about 5-6 hours, sodium chloride is filtered off. After removal of n-butanol and reaction work up the above-described product is obtained in high yields. ##STR30##
