Reaction Steps

To s solution of 5-bromo-3-(1-methyl-2-(S)-pyrrolidinylmethoxy)-pyridine (272 mg, 1.00 mmol) in benzene (2.0 mL) were added sodium carbonate (2.0 M, 1.0 mL), tetrakis(triphenylphosphine)palladium(0) (35 mg, 0.03 mmol) and 4-methoxyphenylboronic acid (228 mg, 1.30 mmol). The reaction mixture was refluxed overnight, then cooled to room temperature. Water (2 mL) was added, and solid sodium bicarbonate was added until the aqueous layer was saturated. The mixture was extracted with EtOAc, which was dried over MgSO4, filtered and concentrated. The residue was chromatographed on a silica gel column, eluting with NH4OH/MeOH/EtOAc 0:1:9 and 1:10:90 to afford a light yellowish oil (174 mg, 58%).
