Reaction Steps

6.5 g of 3-chloro-4-methoxyphenylboronic acid, 5.0 g of methyl 5-bromonicotinate, 1.3 g of tetrakis(triphenylphosphine)palladium(0), and 22.6 g of Cs2CO3 were stirred in 325 ml of DMF and 65 ml of water for 3 h at 45° C. The reaction mixture was then poured into 750 ml of water and extracted three times using 300 ml of EA each. The combined organic layers were then washed twice using 150 ml of water each. The organic layer was then dried using MgSO4 and evaporated. Chromatography on silica gel using EA/HEP (gradient) yielded 2.4 g of the title compound, colorless oil.
