Procedure

Quetiapine free base (5.0 g) was dissolved in isopropyl alcohol (50 ml) at room temperature. This was followed by addition of 98% sulfuric acid (1.28 g) at 30 to 35° C. The resulting gummy mass was heated to reflux and maintained for 15 minutes. The resulting mass was cooled at 25-30° C. and stirred for 1 hour. The precipitated product was collected by filtration, washed with isopropyl alcohol (25 ml) and dried to give the title compound as off white powder (5.88 g).
