Reaktionsschritte

4-Nitrobenzylphosphonic acid and 2,2-diethyl-1,3-propanediol were treated in the same manner as in Reference Example 20 to yield 5,5-diethyl-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 159°-160° C.
