Versuchsvorschrift
A mixture of the dihydrochloride salt of (R)-octahydropyrido[1,2-a]pyrazine (649 mg, 3.05 mmol), diisopropylethylamine (1.17 ml, 6.72 mmol), 3-chloro-6-(4-trifluoromethylphenyl)-pyridazine (290 mg, 1.12 mmol) and dimethylsulfoxide (1 ml) was heated in a closed vessel at 160° C. for 40 min. The reaction mixture was cooled to room temperature, diluted with dichloromethane (10 ml) and washed with water (2×15 ml) and brine (15 ml). The organic layer was dried over magnesium sulphate. The solvent was removed in vacuo to give 398 mg of the title compound as the free base.
