hexahydro s triazine the structure was confirmed by proton nuclear magnetic resonance mass spectroscopy and infrared spectroscopy five ml 0 06 mole of chloroacetyl chloride and 30 ml of 1 2 dichloroethane were placed in a 200 ml flask equipped with a condenser an addition funnel and a mechanical stirrer this solution was heated to reflux and a solution of 20 ml of 1 2 dichloroethane and 4 14 g 0 02 mole of n n n 34 tris allyl hexahydro s triazine was added dropwise with stirring the reaction mixture was then heated an additional 15 minutes at reflux the reaction mixture was stripped under reduced pressure to yield 9 8 g of the desired product the structure was confirmed by proton nuclear magnetic resonance mass spectroscopy and infrared spectroscopy 6 3 grams g 0 062 mole of triethylamine in 50 ml of dichloromethane and 5 2 g 0 031 mole of o o diethylaminomethylphosphonate were placed in a 200 ml flask equipped with an addition funnel and a magnetic stirrer the solution was cooled to about 5 u00b0 c in an ice bath and 5 8 g 0 031 mole of n allyl n chloromethylchloroacetamide in 25 ml of dichloromethane were added.
