実験手順

The ammonium salt of atorvastatin was synthesized by preparing a stock solution of the free acid of atorvastatin (U.S. Pat. No. 5,273,995) in acetonitrile (ACN) (0.634 g in 25 mL of ACN). A solution was prepared by dissolving 12.04 mg of ammonium hydroxide (1.0 equivalents) in acetonitrile (0.5 mL). The stock solution of atorvastatin free acid (2.24 mL) was added to the counterion solution with stirring. If a gel formed, additional acetonitrile and water was added as necessary. After 2 days of stirring at ambient temperature, the solids were isolated by vacuum filtration using a 0.45 μm nylon 66 membrane filter. The solids were rinsed with acetonitrile and air dried at ambient conditions to afford atorvastatin ammonium.
