Procedure

A 100 ml round bottom flask was loaded with fluvastatin methyl ester (4.0 g, 9.4 mmole), water (32 ml) and NaOH (0.39 g). The mixture was stirred for 3 days at room temperature then extracted with ethyl acetate (32 ml, 16 ml). The aqueous solution was evaporated, propan-2-ol (40 ml) was added and the mixture was stirred at room temperature over night. Precipitation occurred after scraping the mixture with spatula and stirring for another day. The product was isolated by filtration under nitrogen flow, washed with propan-2-ol (20 ml) and dried at 50EC in a vacuum oven for 24 h to obtain 1.28 g (31%) of fluvastatin sodium crystal Form LXXVIII.
