Into an apparatus similar to that in Example 1, were charged 339.5 g (1 mole) of N-(2-hydroxy)hexadecyldiethylenetriamine and 116.1 g (1 mole) of methyl acetoacetate. At 140° to 150° C., 18 g of water and 32 g of methanol were distilled off to obtain 4-(2-hydroxyhexadecyl)aminoethyl-7-methyl-3,6-dihydro-2H-1,4-diazepin-5-one.
