(3,4,5,6-Tetrahydro-1H-pyrrolo[3,4-c]pyrrol-2-yl)(2-trifluoromethylphenyl)methanone trifluoroacetate (example 1b) (500 mg, 1.26 mmol), 3-chloro-6-phenethyloxypyridazine (example 4a) (296 mg, 1.26 mmol), tris(dibenzylideneacetone)dipalladium(0)chloroform adduct (67.9 mg, 65.6 μmol), (R)-(+)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (81.7 mg, 131 μmol) and cesium carbonate (1.645 g, 5.048 mmol) were stirred in 5 ml of dioxane under an argon atmosphere at 80° C. for 4 h. The reaction mixture was concentrated and admixed with ethyl acetate and water, and the organic phase was removed, concentrated and purified by preparative HPLC (PR18, acetonitrile/water 0.1% TFA). Yield: 104 mg (14%), M+H+: 481.2.
