実験手順
To a solution of tetraethyl 3-aminooctane-1,1-bisphosphonate (0.45 g, 1.12 mmol) in dry dichloromethane (1.1 mL) was added bromotrimethylsilane (1.05 mL, 7.85 mmol) via syringe. After 18 hours, the mixture was concentrated under vacuum. To the residue was added 3N NH4OH (8 mL) which was stirred for 30 minutes at room temperature. The solvent was removed in vacuo and the residue concentrated from methanol (2 mL) to give 0.40 g of 3-aminooctane-1,1-bisphosphonic acid, triammonium salt as a white powder.
