Tetrahydrofuran → 2-Iodo-3-(2-thiophen-3-ylethoxy)-pyridine

Participants

Reaction Steps

To a solution containing 2-iodo-3-hydroxypyridine (1.85 g, 8.37 mmol), 2-(3-thienyl)ethanol (1.20 mL, 10.9 mmol), and triphenylphosphine (2.85 g, 10.9 mmol) in tetrahydrofuran (46.2 mL, 5.70 mmol) was added diisopropyl azodicarboxylate (2.14 mL, 10.9 mmol) dropwise. The reaction mixture was stirred at room temperature for 18 h. The reaction mixture was concentrated and purified by flash chromatography EtOAc/Hex (0-100%) eluted at 30% to give 2-Iodo-3-(2-thiophen-3yl-ethoxy)-pyridine (yield 90%). MS: (ESI+) 332.2
