Into an apparatus similar to that in Example 1, were charged 313.5 g (1 mole) of N-(2-hydroxy)tetradecyldiethylenetriamine and 158.1 g (1 mole) of butyl acetoacetate. At 150° to 160° C. and under a reduced pressure of 50 mmHg, 18 g of water and 74 g of butanol were distilled off to obtain 4-(2-hydroxytetradecyl)aminoethyl-7-methyl-3,6-dihydro-2H-1,4-diazepin-5-one.
