実験手順
N-Iodosuccinimide (1.3 g, 5.8 mmol) was added to a 0° C. solution of 4-chloro-1H-pyrrolo[3,2-c]pyridine (0.60 g, 3.9 mmol) in N,N-dimethylformamide (10 mL). The reaction mixture was stirred at room temperature for 18 hours, whereupon it was concentrated in vacuo. Purification via silica gel chromatography (0% to 50% ethyl acetate in petroleum ether) afforded the product as a yellow solid. Yield: 900 mg, 3.2 mmol, 82%. 1H NMR (400 MHz, CDCl3) δ 8.10 (d, J=5.5 Hz, 1H), 7.42 (d, J=2.5 Hz, 1H), 7.34 (d, J=5.8 Hz, 1H).
