実験手順
4-Nitrobenzylphosphonic acid and 2-butyl-2-ethyl-1,3-propanediol were treated in the same manner as in Reference Example 20 to yield 5-butyl-5-ethyl-2-(4-nitrobenzyl)-1,3,2-dioxaphosphorinan-2-oxide, which was then recrystallized from ethanol-hexane to yield colorless prisms having a melting point of 111°-112° C.
