A mixture consisting of 42 mg of 4-[(E)-2-(5-bromopyridin-2-yl)vinyl]-2-methyloctahydropyrrolo[3,4-a]indolizine-1,3-dione (from Example 6, racemic mixture 1), 2.5 mg of tetrakis(triphenylphosphine)palladium(0), 25 mg of 3-trifluoromethylphenylboronic acid, 37 mg of potassium carbonate, 1.5 ml of toluene, 0.3 ml of ethanol and 0.75 ml of water is stirred at 100° C. for 5 h. After cooling, the mixture is taken up in 20 ml of water and the product is extracted by shaking with 20 ml of ethyl acetate. After drying and concentration of the organic phase, an oil is obtained. The crude product is purified by column chromatography (silica gel, MeOH:DCM=1:99).
