Reaction Conditions:
with sodium hydroxide in water;acetonitrile at 20;
Steps:
14 Example 14
Pantoprazole (5 g, 25.6 mmol) and 47% NaOH (1 eq.) are added to acetonitrile (25ml) and stirred at room temperature. After 3 h, the mixture becomes clear, and crystals beginto form. The mixture is allowed to stand overnight. The crystals are filtered and dried at50°C under 10 mm Hg vacuum. The crystals are determined to be the sesquihydrate form ofpantoprazole sodium by PXRD and are found to have a water content of 7.0% by Karl Fisheranalysis. Yield: 95%.
