実験手順
A solution of amorphous ibandronic acid (4.5 g) in water (11 ml) and sodium hydroxide (0.56 g, solid) was stirred at room temperature. The solution was added dropwise into acetone (100 ml). The resulting precipitate was stirred at room temperature for 16 hours. The precipitate was isolated by vacuum filtration, washed with acetone (2×10 ml), and dried in a vacuum oven at 50° C. for 24 hours to obtain 4.8 g of ibandronate sodium crystal form Q.
