Reaction Steps

A solution of 1-(4-{1-ethyl-1-[3-methyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-propyl}-2-methyl-phenoxy)-3,3-dimethyl-butan-2-one (Example 30-(2); 0.06 g, 0.12 mmol), (5-bromo-pyridin-3-yl)acetic acid methyl ester (Example 24-(2); 42.0 mg, 0.18 mmol), tetrakistriphenylphosphine palladium (19.6 mg, 0.017 mmol) and potassium phosphate (38.7 mg, 0.18 mmol) in N,N-dimethylformamide (0.3 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 (52.8 mg, 83%).
