Procedure

Rabeprazole (10 g) was suspended in 30 ml THF and sodium hydroxide solution (1.11 g sodium hydroxide dissolved in 1 ml water) was added at 25-30° C. Reaction mass was stirred for 30 minutes at 25-30° C. Added activated charcoal (1.0 g) and stirred for 30 minutes at 25-30° C. Filtered and washed charcoal bed with THF (20 ml). Distilled out THF under reduced pressure at 30-35° C. completely. Residue was dissolved in THF (20 ml). In a separate R B flask charged n-heptane (100 ml) at 25° C. Added slowly above reaction mass in 15-20 minutes at 25-30° C. Stirred at 25-30° C. for 2 hours. The product was filtered off under nitrogen atmosphere and wet cake was washed with n-heptane (2×20 ml). Dried under vacuum at 50° C. for 20-24 hours to obtain amorphous Rabeprazole sodium.
