実験手順
Into an apparatus similar to that in Example 1, were charged 104.2 g (1 mole) of N-hydroxyethylethylenediamine and 130.1 g (1 mole) of ethyl acetoacetate. At 150° to 160° C., 18 g of water and 46 g of ethanol were distilled off. Then, after addition of 200.3 g (1 mole) of lauric acid, the esterification was effected at 200° to 210° C. to distil off 18 g of water and to obtain 4-lauroyloxyethyl-7-methyl-3,6-dihydro-2H-1,4-diazepin-5-one.
