実験手順

m-Chloroperbenzoic acid (1.55 g, 6.29 mmol) was added portionwise to a solution of 1.0 g (3.02 mmol) of 3-iodo-4-(2-(thiophen-3-yl)ethoxy)pyridine in 150 ml of methylene chloride. The mixture was stirred for 18 hours then mixed with 100 ml of 1 M aqueous sodium carbonate. The organic layer was separated and the aqueous one was extracted 2 times with 10 ml of methylene chloride. Combined organic extracts were washed with brine and dried over sodium sulfate. The solution was concentrated in vacuum to give 3-iodo-4-(2-(thiophen-3-yl)ethoxy)pyridine 1-oxide (1.01 g, 92%). MS: (ESI+) 348.0
