Procedure

Fluvastatin methyl ester (3.0 g) was added to cyclohexane (60 ml) and the slurry was heated to reflux. A solution of NaOH (1 eq.) in MeOH (3 ml) was added to the slurry solution which became clear. After 15 min. a precipitate formed. After another hour, the mixture was cooled to room temperature and cyclohexane (40 ml) was added. The mixture was stirred over night. The product was isolated by filtration under nitrogen, washed with cyclohexane (90 ml) and dried at 50EC in a vacuum oven for 24 h to yield 2.73 g (90%) of amorphous fluvastatin sodium.
