Reaction Steps

Fluvastatin methyl ester (2.0 g) was added to a solution of NaOH (1 eq.) in ethanol (15 ml). The mixture was stirred at about 70° C. for 1.75 h, after which the starting material was not detected by HPLC. Then, acetone (40 ml) was dripped into the solution and the mixture was cooled slowly to room temperature and stirred overnight. The product was isolated by filtration under nitrogen, washed with acetone (20 ml) and dried at 50° C. in a vacuum oven for 24 h to obtain 1.54 g (75.6%) of fluvastatin sodium Form VI.
