Procedure

1 g (3.2 mmoles) of olanzapine base is dissolved in 20 cm3 of tetrahydrofuran by boiling in an apparatus equipped with a reflux condenser. Subsequently 3.4 g of hydrogen chloride solution in 1,4-dioxane (34.5 m/m %) are dropped to it. The mixture is cooled in ice-water for 10 minutes and the precipitated yellow product is filtered off. Thus 1.20 g (97%) of the title compound is obtained.
