Reaction Steps

A solution of (E)-3-ethyl-1-(4-{1-ethyl-1-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-propyl}-2-methyl-phenyl)-1-penten-3-ol (Example 39-(5); 50.0 mg, 0.10 mmol), (6-chloro-pyridin-3-yl)acetic acid ethyl ester (31.4 mg, 0.15 mmol), tetrakistriphenylphosphine palladium (16.9 mg, 0.0146 mmol) and potassium phosphate (33.4 mg, 0.15 mmol) in N,N-dimethylformamide (0.30 mL) was stirred with microwave heating at 140° C. for 10 minutes. The reaction mixture was filtered through cotton plug, and the residue was purified by silica gel chromatography (30 to 40% ethyl acetate/hexane) to give the title compound (37.6 mg, 69%).
