Participants

Reaction Steps

In a 100 ml flask were placed Fluvastatin methyl ester (2.0 g) and a solution of NaOH (0.19 g) in EtOH (5 ml). The mixture was stirred at reflux for 3.5 h and propan-2-ol (40 ml) was added. The slurry was cooled to room temperature and stirred over night. The product was isolated by filtration under nitrogen, washed with propan-2-ol (20 ml) and dried at 50EC in a vacuum oven for 24 h to obtain 1.93 g (95%) of fluvastatin sodium crystal Form XXXIX.
