Participants

Reaction Steps

A solution of ([1,1 '-Biphenyl]-2-ylmethyl)phosphonic acid dimethyl ester (Compound 6, 515 mg, 1.87 mM) in concentrated hydrochloric acid (5 mL) is heated at reflux temperature for six hours. The reaction is then allowed to stand at room temperature until a white precipitate is formed. The aqueous HCl is removed under reduced pressure. The white solid is recrystallized from water to yield 300 mg of title compound as white crystals, mp 168.5°-169° C.
