Reaction Steps
In water (5 ml) was dissolved 3-methoxypropylaminomethylenebisphosphonic acid trisodium salt trihydrate (1.0 g), and the solution was passed through a column packed with Amberlite CG-50 (H+ type, 75 ml). Elution was conducted with water. From the acidic fraction thus eluted, 3-methoxypropylaminomethylenebisphosphonic acid monosodium salt hemihydrate (0.67 g, 87%) was obtained as colorless prisms, m.p. 277°-279° C.
