Nitric Acid → Quetiapine Nitrate

Participants

Reaction Steps

Quetiapine free base (5.0 g) was dissolved in acetone (50 ml) at room temperature. This was followed by the addition of 68 to 72% nitric acid (0.7 g) at 20 to 25° C. The resulting precipitated solid was stirred for 1 hour. The precipitated product was collected by filtration, washed with acetone (15 ml) and dried to give the title compound as white powder (4.0 g).
