Reaktionsschritte
4-Nitrobenzylphosphonic acid and 2,4-pentanediol were treated in the same manner as in Reference Example 20 to yield 4,6-dimethyl-2-(4-nitrobenzyl)-1,3,2-dioxaphosphorinan-2-oxide, which was then recrystallized from ethanol-hexane to yield colorless needles having a melting point of 152°-153° C.
