N-Benzyl-N-methylpiperidin-4-amine (3.947 mmol, 1.0 eq.), 5-bromo-2-methoxypyridine (614 μl, 4.737 mmol, 1.2 eq.) and t-BuONa (757 mg, 7.894 mmol, 2.0 eq.) were dissolved in toluene (12 ml) and degassed with argon. Xantphos (136 mg. 0.237 mmol, 0.06 eq.) and Pd2(dba)3 (72 mg, 0.079 mmol, 0.02 eq.) were then added and the mixture was heated for 4 hours at 90° C. After monitoring by TLC, the reaction mixture was concentrated under reduced pressure and purified by column chromatography (silica gel, 3% MeOH in DCM). Yield: 36% (450 mg, 1.447 mmol)
