実験手順

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, 0.88 g (0.012 mole) of n-butylamine and 20 ml hexamethyldisilazane in 40 ml freshly distilled dry dioxane is refluxed for 17 hours. After cooling to room temperature, 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 1.02 g (87 percent) of 5-butylamino-6H-1,2,4-oxadiazin-3(2H)-one.
