Procedure

In a 3 neck flask were placed fluvastatin methyl ester (3.0 g) and MeOH (30 ml). The mixture was heated to reflux for dissolution and NaOH (0.42) was added in two portions. Precipitant was appeared at reflux temperature and wasn't dissolved after addition of another 45 ml of MeOH during 4 h. The slurry mixture was cooled to room temperature and stirred over night. The precipitant was dissolved, acetone (150 ml) was added and the mixture was stirred at room temperature for 22 h. The product was isolated by filtration under nitrogen, washed with acetone (35 ml) and dried at 50EC in a vacuum oven for 22.5 h to obtain 1.68 g of fluvastatin sodium crystal Form LXIV.
