5-methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridinyl)-methyl]sulfinyl]-1H-benzimidazole potassium salt (100 g) was taken in water (500 ml) and was stirred at room temperature for 10-15 minutes. The pH was adjusted to 10-11 with acetic acid at and the mixture was stirred for half an hour 20-25° C. Methanol (100 ml) was added. Aqueous solution of magnesium chloride hexahydrate (20.3 g dissolved in 100 ml) was then added to the above mixture at room temperature under stirring. The mixture was stirred for 60 minutes at room temperature. The resulting solid was filtered, washed with methanol and water.
