実験手順
3-Iodo-5-nitropyridin-2-ol (3.00 g, 0.0113 mol) was heated to reflux in phosphoryl chloride (15 mL, 0.1609 mol) for 4 hours. The reaction was quenched in ice/water and was neutralized with Na2CO3. The reaction was extracted with ethyl acetate and the organic extracts were washed with water, saturated NaCl, dried (MgSO4) and stripped in vacuo to give the product, which was used in the next reaction without purification.
