Versuchsvorschrift
4-Nitrobenzylphosphonic acid and 1,4-butanediol were treated in the same manner as in Reference Example 20 to yield 2-(4-nitrobenzyl)-1,3,2-dioxaphosphepan-2-oxide, which was then recrystallized from ethanol-hexane to yield colorless needles having a melting point of 136°-137° C.
