A mixture of 0.17 g, (0.61 mmol) 2-[3-(2-naphthyl)-8-azabicyclo[3.2.1]oct-2-en-8-yl]ethylamine, 0.13 g (0.55 mmol) 8-bromo-6-methoxyquinoline, 30 mg (0.03 mmol) Pd2(dba)3, 20 mg (0.08 mmol) 2-(di-t-butylphosphino)biphenyl and 10 mL PhMe is stirred at 23° C. for 16 h. The reaction mixture is poured into 100 mL of H2O and extracted 3×50 mL EtOAc. The combined organics are washed with 1×100 mL H2O, 1×100 mL brine, dried over MgSO4, filtered, and the volatiles are evaporated. The crude product is subjected to flash chromatography on SiO2, eluting with EtOAc to EtOAc/2M NH3 in MeOH (40/1), to give the title compound as an off-white solid. This solid is dissolved in 4 mL of absolute EtOH and treated with 0.01 g (0.14 mmol) (CO2H)2 to give 0.07 g (0.13 mmol, a 23% yield) of the oxalate salt of the title compound as a dark green solid: mp: 179-182 C; MS (ES) m/z 436 (MH)+.
