Versuchsvorschrift
A free form (1 g) of (R)-3-[2-(2-hydroxymethylpyrrolidin-1-yl)ethyl]-5-methyl-2H-isoquinolin-1-one was measured, ethanol (40 ml) was added and the mixture was completely dissolved by heating under reflux. Thereto was added commercially available 85% phosphoric acid (200 μL) and the mixture was left stirring at room temperature for 1 hr. The precipitate was collected by filtration and dissolved again in water (1 mL) at 80° C. Ethanol (8 mL) was added and the mixture was left standing at room temperature for 1 hr. The resulting precipitate was collected by filtration and dried under reduced pressure at 50° C. for 9 hr to give the title compound (838 mg).
