Reaction Steps

Fluvastatin methyl ester (3.0 g) was dissolved in acetone (30 ml) and NaOH (0.29 g) partially dissolved in acetone (0.75 ml) was added. The mixture was stirred at room temperature overnight. The product was isolated by filtration under nitrogen, washed with acetone (40 ml) and dried at 50EC in a vacuum oven for 24 h to obtain 2.31 g (76.2%) of fluvastatin sodium crystal Form I.
