Versuchsvorschrift

N,N-Dimethylformamide (0.7 mL) was added to 4-(4-{1-ethyl-1-[3-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-propyl}-2-methyl-phenyl)-1,1,1-trifluoro-2-trifluoromethyl-butan-2-ol (Example 27-(2); 60 mg, 0.105 mmol), (6-chloro-pyridin-3-yl)acetic acid ethyl ester (40 mg, 0.201 mmol), tetrakis(triphenylphosphine)palladium (0) (23 mg, 0.02 mmol) and potassium phosphate (63.9 mg, 0.30 mmol). The mixture was stirred with microwave heating at 140° C. for seven minutes in a nitrogen atmosphere. The reaction mixture was concentrated under reduced pressure. The residue was purified by preparative TLC (hexane/ethyl acetate=5/1) to give the title compound (26 mg, 41%).
