Into an apparatus similar to that in Example 1, were charged 299.5 g (1 mole) of N-tetradecyldiethylenetriamine and 116.1 g (1 mole) of methyl 2-formylpropionate. At 130° to 135° C., 18 g of water and 32 g of methanol were distilled off to obtain 4-tetradecylaminoethyl-6-methyl-3,6-dihydro-2H-1,4-diazepin-5-one.
