Reaction Steps

To a solution of 5-bromo-3-(1-methyl-2-(S)-pyrrolidinylmethoxy)pyridine (272.0 mg, 1.0 mmol) in acetonitrile (3.0 mL) and triethylamine (2.5 mL) was added methyl acyrate (0.360 mL, 4.0 mmol), palladium acetate (23.0 mg, 0.1 mmol) and tri-o-tolylphosphine (122.0 mg). After being heated in a sealed tube at 100° C. overnight, the resulting mixture was cooled to room temperature. A minimum amount of saturated sodium bicarbonate was added to free the amine, and the mixture was extracted with EtOAc, dried (MgSO4), and concentrated. The residue was chromatographed on a silica gel column, eluting with CHCl3 /MeOH 10:1 to afford a light yellowish oil (205 mg, 74%).
