Reaction Steps

Diethyl (3-iodo-5-nitropyridin-2-yl)malonate (0.250 g, 0.000612 mol) was heated in 6 M sulfuric acid (3 mL) at 100° C. for 16 hours. The reaction was neutralized with solid Na2CO3, extracted with EtOAc and the organic extracts were washed with water, saturated NaCl, dried (MgSO4) and stripped in vacuo. NMR analysis indicated that it was clean enough for the next reaction. 1H NMR (400 MHZ, CDCl3): δ 9.27 (d, 1H), 8.82 (d, 1H), 2.87 (s, 3H); MS (ES) (M+H)=265.
