Reaction Steps

A solution of 2-(4-{1-ethyl-1-[3-methyl-4-(4,4,4-trifluoro-3-methoxymethoxy-3-trifluoromethyl-1-butynyl)-phenyl]-propyl}-2-methyl-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane (Example 25-(4); 47.7 mg, 0.1 mmol), (5-bromo-pyridin-3-yl)acetic acid methyl ester (Example 24-(2); 26.8 mg, 0.11 mmol), tetrakistriphenylphosphine palladium (12.5 mg, 0.0108 mmol) and potassium phosphate (24.7 mg, 0.11 mmol) in N,N-dimethylformamide (0.25 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 (36.0 mg, 72%).
