実験手順
A solution of the bisalkylated phosphinic acid ester 10 (170 mg, 0.32 mmol) in 37% aqueous hydrochloric acid (20 ml) is heated to a temperature of about 100° C. for 6 hours. After concentration of the reaction solution under reduced pressure and repeated coevaporation with methanol and toluene, the phosphinic acid hydrochloride 16 (101 mg, 93% of theory) is obtained.
