Procedure

Sertraline base (2.7 g) was suspended in 27 mL of water. This mixture was heated to 80° C. and treated with hydrochloric acid until about pH 1 was reached. A clear solution was obtained which on cooling gave a precipitate. After 2 hours stirring at room temperature the solid was isolated by filtration. This solid was characterized by powder x-ray diffraction (see FIG. 7). Drying for 24 hours at ˜50° C. yielded 2.32 g (76.8%) of sertraline hydrochloride Form IX, characterized by powder x-ray diffraction, infra-red absorption, differential scanning calorimetry, and thermal gravimetric analysis as set forth above and depicted in FIGS. 8, 10, and 12.
