2-Chloropyridine → 2-(2-{4-[(Butan-2-yl)oxy]phenoxy}propoxy)pyridine

Participants

Reaction Steps

To a mixture of sodium hydride (0.08 g) in 5 ml of tetrahydrofuran (THF) and 2 ml of hexamethylphosphoramide (HMPA), cooled in an ice bath, is added, dropwise, 2-methyl-2-[4-(1-methylpropoxy)phenoxy]ethanol (0.63 g). The mixture is stirred at RT for 2 hours, after which a solution of 2-chloropyridine (0.38 g) in 5 ml of THF is added and the mixture is stirred at 60° for 3 hours. The THF is then removed by rotoevaporation and the residue is purified by column chromatography on silica gel to give the product, 2-{2-methyl-2-[4-(1-methylpropoxy)phenoxy]ethoxy}pyridine, MS m/e 302 (M+).
