Into an apparatus similar to that in Example 1, were charged 118.2 g (1 mole) of N-hydroxypropylethylenediamine and 158.2 g (1 mole) of isopropyl 3-formyl-2-methylpropionate. From the apparatus, 18 g of water and 60 g of isopropyl alcohol were distilled off. Then, 340.5 g (1 mole) of behenic acid was charged and 18 g of water was distilled off at 180° C. and under a reduced pressure of 70 mmHg to obtain 4-behenoyloxypropyl-6-methyl-2,3,6,7-tetrahydro-1,4-diazocin-5-one.
