Procedure

A solution of 1.16 g (0.010 mole) of 6H-1,2,4-oxadiazin-3,5(2H,4H)-dione, 5 mg of ammonium sulfate, 2.22 g (0.012 mole) of dodecylamine and 20 ml of hexamethyldisilazane in 40 ml of freshly distilled dry dioxane is refluxed for 17 hours. After cooling, the dioxane and hexamethyldisilazane are removed in vacuo and the syrupy residue is dried on a vacuum pump for 2 hours. The resulting semi-solid residue is triturated with 100 ml of petroleum ether and filtered to yield 2.5 g (88 percent) of 5-dodecylamino-6H-1,2,4-oxadiazin-3(2H)-one.
