Procedure
Reacting the 4-benzyloxy-5-ethyl-2-methoxy-phenylboronic acid (5) with 2-bromo-6-(2,5-dimethylpyrrol-1-yl)pyridine, sodium carbonate and tetrakis(triphenylphosphine)palladium(0) in a polar solvent such as methanol/water, ethanol/water, or tetrahydrofuran (THF)/water, preferably ethanol/water, at a temperature from about room temperature to about the reflux temperature of the reaction mixture, preferably at about the reflux temperature, yields 2-(4-benzyloxy-5-ethyl-2-methoxy-phenyl)-6-(2,5-dimethyl-pyrrol-1-yl)-pyridine (6).
