Procedure

A 250 ml round bottom flask was loaded with fluvastatin tert-butyl ester (4.0 g, 8.56 mmole), NaOH (0.35 g), water (48 ml) and EtOH (120 ml) which were added gradually till clear solution was obtained. The mixture was stirred for 2.5 h then the EtOH was evaporated. The volume of the water was completed to 8 vol. and the mixture was extracted with EtOAc (2×30 ml). The aqueous solution was evaporated to obtain 6.07 g and ACN (60 ml) was added. The solution was stirred at room temperature over night. The product was isolated by filtration under nitrogen, washed with ACN (20 ml) and dried at 40° C. in a vacuum oven for 24 h to obtain 2.86 g (77.1%) of fluvastatin sodium crystal form LXXX.
