A solution of 2-(4-{1-ethyl-1-[3-methyl-4-(1-trimethylsilanyloxy-cyclopentylethynyl)-phenyl]-propyl}-2-methyl-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (Example 32-(4); 54.1 mg, 0.0968 mmol), (5-bromo-pyridin-3-yl)acetic acid methyl ester (Example 24-(2); 33.4 mg, 0.14 mmol), tetrakistriphenylphosphine palladium (15.6 mg, 0.0135 mmol) and potassium phosphate (30.8 mg, 0.14 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 (45% ethyl acetate/hexane) to give the title compound (38.2 mg, 67%).
