実験手順
Except that the recrystallization-purified 3-[hydroxy(phenyl)phosphinyl]propionic acid obtained in Comparative Example 3 was used in lieu of the rinse-purified 3-[hydroxy(phenyl)phosphinyl]propionic acid, the procedure of Comparative Example 4 was repeated to provide 102.81 g of an ethylene glycol solution of hydroxyethyl 3-[hydroxy(phenyl)phosphinyl]propionate.
