HCID 189280854,6-Dimethyl-2-(4-nitrobenzyl)-1,3,2-dioxaphosphorinan-2-oxide

Procedure

With 4-nitrobenzylphosphonic acid and 2,4-pentanediol, the same procedure as in Reference Example 11 was followed, to yield 4,6-dimethyl-2-(4-nitrobenzyl)-1,3,2-dioxaphosphorinane-2-oxide, which was then recrystallized from ethanol-hexane to yield colorless needles having a melting point of 152° to 153° C.
