Procedure

27 g of dimethoxyphosphinyl-hydroxy-acetic acid butyl ester and 200 ml of 5 N hydrochloric acid are boiled under reflux for 15 hours. The water is distilled off, the product is freed from residual water by azeotropic distillation with toluene and 15.0 g of phosphono-hydroxy-acetic acid are obtained (yield: 85%). 1H-NMR (D2O): δ=4.56 ppm (1H, d, J=18 Hz, P--CH)
