실험 절차

To a solution of 5-bromo-6-chloro-3-(1-BOC-2-(R)-pyrrolidinylmethoxy)pyridine (600 mg, 1.59 mmol) in acetonitrile (5.0 mL) and triethylamine (4.5 mL) was added 5,5-dimethyl-1,3-hexadiene (228 mg), palladium acetate (39 mg) and tri-o-tolylphosphine (205 mg). After being heated in a sealed tube at 100° C. overnight, the resulting mixture was cooled to room temperature. Minimum amount of saturated sodium bicarbonate was added to free the amine hydrochloride salt, and the mixture was extracted with EtOAc, dried (MgSO4), and concentrated. The residue was chromatographed on a silica gel column, eluting with EtOAc:hexane 1:3 to afford the title compound (126 mg, 42% yield).
