YieldReaction ConditionsOperation in experiment
84% With water; acetic acid;Reflux; A mixture of 2,3-difiuoro-4-iodopyridine (from Ark Pharm, 3.0 g, 12 mmol) in acetic acid (30 mL) and water (15 mL) was heated to reflux overnight. Most of the solvent was removed by vacuum and the remaining was neutralized with aq. NaHCCb and extracted by EtOAc. The organic layers were combined, dried and concentrated. The white solid crude product obtained (2.5 g, 84%) was used directly in the next step without further purifications. LCMS calc. for C5H4FINO (M+H)+ m/z = 239.9; found, 240.0
71.4% With acetic acid; In water;Reflux; 2,3-Difluoro-4-iodopyridine (300 mg, 1 .24 mmol) was suspended in acetic acid: water (2:1 , 15 mL). The mixture was heated to reflux and stirred at this temperature overnight. Reaction was concentrated to dryness, and triturated in water (10 mL) for 30 min. The solid was collected via filtration, washed with water (2x10 mL), and pentane (2x20 mL) and dried under vacuum to afford the title compound as a white solid (354 mg, 71.4%). LC-MS m/z 342.0 (M+1 ). 1H NMR (400 MHz, METHANOL-^) delta ppm 6.56 - 6.82 (m, 1 H) 6.83 - 7.18 (m, 1 H).
65.3% With water; potassium hydroxide; In 1,4-dioxane; at 100℃; [00495] To a solution of 2,3-Difluoro-4-iodopyridine (0.250 g, 1.04 mmol) in a mixture of water (1.04 mL, 1.04 mmol) and dioxane (0.10 mL) was added powdered KOH (0.116 g, 2.07 mmol) and heated to 100 °C overnight. The mixture was cooled to room temperature, at which time a white solid crashed out. Water (15 mL) and 3 mL glacial acetic acid were added and the reaction mixture was stirred for 30 min. The aqueous layer was extracted with 4:1 DCM:IPA (3 x10 mL), dried over Na2SO4, filtered and concentrated to afford 3-fluoro-4-iodopyridin-2(1H)-one (0.162 g, 0.678 mmol, 65.3 percent yield) as a white solid.
