With 4-nitrobenzylphosphonic acid and 2-butyl-2-ethyl-1,3-propanediol, the same procedure as in Reference Example 11 was followed, to yield 5-butyl-5-ethyl-2-(4-nitrobenzyl)- 1,3,2-dioxaphosphorinane-2-oxide, which was then recrystallized from ethanol-hexane to yield colorless prisms having a melting point of 111° to 112° C.
