In a'2-liter, S-necked flask equipped with a bulb reflux condenser and sealed stirrer, 23 g. metallic sodiumis added in small increments to 300 g. diethylaminoethanol, while maintaining anhydrous conditions. After the addition iscomplete (during which time the temperature rises to '.70-80- C.), the mixture is stirred for 4 hours; then allowed to remain overnight at room temperature. The undissolved sodium is removed from the reaction vessel and 58 g. cyanuric chloride, dissolved in 300 ml. anhydrous benzene, is added dropwise with stirring over a period of about 2.5 hours. The resulting reaction mixture is stirred at 75-80 C. for 8 additional hours, cooled to room temperature, then poured into 300 ml. cold water. The resulting mixture is transferred to 'a separatory funnel, and the benzene layer is separated, washed with saturated sodium chloride solution, then dried over anhydrous potassium carbonate and filtered. The benzene is removed by distillation at atmospheric pressure, and the unreacted diethylaminoethanol is separated by vacuum distillation; The remaining oil is then distilled in vacuo at 0.3 to 0.5 mm. Hg; and 59 g. product, distilling at l90-2l0 C., is separated. On redistillation, about 45 g. purified 2,4,6-tris(diethylaminoethoxy)-l,3,5- triazine [B. P. 178-182 C. at 0.2 to 0.3 mm.

Vigorous stirring is maintained during the addition as the temperature rises from 25 to 50 C. The temperature is then raised to about 80 C. and vigorous stirring is continued until a test for ionic chlorine indicates substantially complete reaction. The reaction mixture is then cooled to C. and 1 liter 5% aqueous sodium hydroxide is added. The resulting mixture is transferred to a separatory funnel and the aqueous layer is extracted several times with benzene after removing the organic layer. The benzene extracts are combined with the organic layer and the resulting solution is washed with saturated sodium chloride solution, dried over anhydrous potassium carbonate, and filtered. The benzene and diethylaminoethylamine are separated by in vacuo distillation and the residue is vacuum distilled to yield about 124 g. pure 2,4,6-tris(diethylaminoethylamine)-l,3,5-triazine, B.

The benzyl alcohol and excess ethyl bromide are separated by distillation under high vacuum on a steam bath and the oily residue is dissolved in chloroform, then recovered from the solution by adding anhydrous ether. On further trituration with anhydrous ether, the oil solidifies and is separated by filtration, yielding about 29 g. amorphous hygroscopic solid, M. P. -125 C. Recrystallization from ethylene dichloride, followed by desiccator drying under high vacuum over phosphorous pentoxide, yields the purified salt.

The reaction mixture is then heated with a stirring at 60 C. until a test for ionic chlorine indicates substantially complete reaction. The mixture is then cooled, suction filtered, and the filter cake washed with benzene. The combined benzene extracts and washings are heated to remove the solvent. The crude residue is then taken up in a mixture of ether and benzene, washed first with aqueous sodium hydroxide solution, then with saturated sodium chloride solution and dried over anhydrous potassium carbonate.

During the addition, the temperature rises to about 45 C. The clear solution obtained is concentrated by distillation and the resulting viscous liquid is titrated with ether, then filtered. The resulting solid material is dried in a vacuum desiccator over phosphorous pentoxide at 70-75 C. to yield about 44 g. l,3,5-triazino-2,4,6-tris(aminoethylene)- tris-dimethylbenzyl ammonium chloride.

B-diethylaminoethyl mercaptan in 500 ml. benzene. The temperature is maintained below 50 C. (by occasional cooling with ice water) andthe stirring is continued until the evolution of hydrogen ceases. A solution of 61.5 g. cyanuric chloride in 500 ml. anhydrous benzene is then added dropwise with stirring,
and the resulting mixture is heated for 5 hours at gentle reflux. After cooling, the reaction mixture is poured into one liter of water. Thebenzene layer is then separated, washed twice with 10% aqueous sodium chloride and dried over anhydrous potassium carbonate. The benzene is then removed by distillation and the residue is fractionally distilled under reduced pressure to yield the 2,4,6-tris(fi-diethylarninoethylmercapto)-1,3,5-triazine as a viscous oil.

The unreacted benzyl chloride and benzyl alcohol are then separated from the reaction mixture by distillation under reduced pressure. The residual oil is triturated with anhydrous ethyl ether, then filtered to isolate the 1,3,5-triazino-2,4,-6.- tris (mercaptoethylene)-tris-diethylbenzylammonium chloride. The product may be recrystallized from ethylene dichloride, or from a mixture of ethanol and ethyl ether.
