A mixture of 2-chloro-N-isopropyl-6-((2,2,2-trifluoroethoxy)methyl)pyrimidin-4-amine (41 mg, 0.14 mmol), 3-methoxy-4-(6-methylpyridazin-4-yl)aniline (31 mg, 0.14 mmol), cesium carbonate (94 mg, 0.29 mmol), palladium(II) acetate (5 mg, 0.02 mmol) and 2-(dicyclohexyl-phosphino)biphenyl (8 mg, 0.02 mmol) in dioxane (2 mL) was heated under argon at 120° C. for 90 minutes in a microwave reactor. The mixture was filtered through a short silica gel plug which was washed with 10% solution of methanol in ethyl acetate. The eluate was concentrated in vacuum and the residue was purified by preparative HPLC to give the title compound 32 mg (48%).
