Into an apparatus similar to that in Example 1, were charged 339.5 g (1 mole) of N-(2-hydroxy)hexadecyldiethylenetriamine and 130.1 g of ethyl 2-formylpropionate. At 140° to 150° C., 18 g of water and 46 g of ethanol were distilled off to obtain 4-(2-hydroxyhexadecyl)aminoethyl-6-methyl-3,6-dihydro-2H-1,4-diazepin-5-one.
