Reaction Steps

4-Nitrobenzylphosphonic acid and 2,2-dimethyl-1,3-propanediol were treated in the same manner as in Reference Example 20 to yield 5,5-dimethyl-2-(4-nitrobenzyl)-1,3,2-dioxaphosphorinan-2-oxide, which was then recrystallized from ethanol-hexane to yield colorless plates having a melting point of 176°-177° C.
