实验过程

To a 12 liter, 3 neck round-bottom flask equipped with mechanical stirrer, 4287ml of methylene chloride, 2553ml water and 638.3gms sertraline mandelate were combined. A 10% sodium hydroxide solution, 383ml, was then added and the resulting two clear layers were separated. The aqueous layer was further extracted with 2×586ml of methylene chloride. The combined methylene chloride layers were washed with 2×1110ml water and separated. The methylene chloride solution was atmospherically distilled and displaced with isopropanol to a final volume of 4440ml. 53.7ml water were added to the resulting isopropanol solution. The solution was cooled to 50° C. and seeded with sertraline hydrochloride - Form I. Hydrogen chloride, 208.1ml of 6.37 molar, in aqueous isopropanol was added to the clear solution to give a thick white slurry. Additional isopropanol 1500ml was added and the material stirred for three hours at 50° C., then cooled to room temperature overnight. The solution was distilled at atmospheric pressure to remove 1,900ml. Isopropanol was then added (1000ml) to lower the water content. The mixture was then cooled and filtered to yield desired crystalline polymorph (Form I).
