Participants

Reaction Steps

N-(4-Methoxybenzyl)-N,3,3-trimethylpiperidin-4-amine (5.17 mmol, 1 eq) and 4-bromopyridine hydrochloride (1.509 g, 7.76 mmol, 1.5 eq) were dissolved in n-butanol (40 ml) and DIPEA (4.26 ml, 25.87 mmol, 5 eq) and refluxed for 16 h. After monitoring by thin-layer chromatography, the reaction solution was concentrated under reduced pressure. After purification by column chromatography (silica gel, 5% MeOH in dichloromethane), the desired product was obtained in the form of a white solid. Yield: 40% (700 mg, 2.06 mmol).
