Reaction Steps

Dichloro[1,1′-bis(diphenylphosphino)ferrocene]-palladium(II)dichloromethane adduct (12 mg, 0.015 mmol), acetonitrile (500 μL), 2.0 M sodium carbonate (aq) (250 μL), 1-((1S,2R,4R)-bicyclo[2.2.1]heptan-2-yl)-4-(5-bromo-2-methoxyphenyl)piperidine hydrochloride (compound no. 187) (60 mg, 0.15 mmol) and 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (31 mg, 0.15 mmol) were combined in a microwave vial. The vial was flushed with nitrogen, capped and microwaved at 140° C. for 20 min. The reaction was diluted with methanol (750 μL), mixed well and then filtered (Whatman 0.20 μM PTFE) and subjected to reverse-phase HPLC purification (2-40% CH3CN/0.08% TFA) to yield [4-(3-(1-((1S,2R,4R)-bicyclo[2.2.1]heptan-2-yl)piperidin-4-yl)-4-methoxyphenyl) pyridine] (compound no. 124) as the TFA salt. LC/MS (RP-C18, 10-99% CH3CN/0.05% TFA gradient over 5 min) m/z 363.4 [M+H]+, retention time 1.67 min.
