A solution of (E)-3-ethyl-1-(4-{1-ethyl-1-[3-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-propyl}-2-methyl-phenyl)-1-penten-3-ol (Example 28; 49.3 mg, 0.1 mmol), (5-bromo-pyridin-3-yl)acetic acid methyl ester (Example 24-(2); 34.7 mg, 0.15 mmol), tetrakistriphenylphosphine palladium (16.2 mg, 0.014 mmol) and potassium phosphate (31.9 mg, 0.15 mmol) in N,N-dimethylformamide (0.27 mL) was stirred with microwave heating at 140° C. for 10 minutes. The reaction mixture was filtered through cotton plug, and the mixture was purified by silica gel chromatography (40% ethyl acetate/hexane) to give the title compound (37.1 mg, 71%).
