Reaction Steps

In a 100 ml flask were placed Fluvastatin methyl ester (3.0 g), MeOH (20 ml) and NaOH (0.29 g). After a clear solution was obtained propan-2-ol (80 ml) was added and the solution was stirred at room temperature over night. A little precipitation occurred, propan-2-ol (40 ml) was added and the solution was stirred at room temperature for another night. The product was isolated by filtration under nitrogen, washed with acetone (35 ml) and dried at 50° C. in a vacuum oven for 22.5 h to obtain 0.92 g of fluvastatin sodium crystal Form LXV.
