Into an apparatus similar to that in Example 1, were charged 104.2 g (1 mole) of N-hydroxyethylethylenediamine and 116.1 g (1 mole) of methyl 3-formylpropionate. At 130° C., 18 g of water and 32 g of methanol were distilled off. After adding 340.5 g (1 mole) of behenic acid, esterification was carried out at 210° to 220° C. to obtain 4-behenoyloxyethyl-2,3,6,7-tetrahydro-1,4-diazocin-5-one.
