Versuchsvorschrift

To a suspension of NaH (1.87 g, 77.9 mmol) in THF (26 mL) under nitrogen was slowly added EtOH (80 mL, Aldrich>99.5%, 200 proof) and the resulting homogeneous solution was stirred for 10 minutes. The sodium ethoxide solution was then added to a mixture of 3-Chloro-4-(2-fluoro-4-(1-(4-fluorophenyl)-4-iodo-2-oxo-1,2-dihydropyridine-3-carboxamido)phenoxy)picolinamide (37.3 g, 59.9 mmol) in THF (100 mL) and EtOH (46 mL), and the resulting mixture was stirred at room temperature for 1 h before being concentrated in vacuo. The residue was suspended in water (500 mL) and the mixture was sonicated and stirred for about 1 h at room temperature until the remaining solid became a filterable powder. The resulting powder was collected, triturated with ethyl ether (50 mL) and dried under high vacuum for 48 h to afford 3-Chloro-4-(4-(4-ethoxy-1-(4-fluorophenyl)-2-oxo-1,2-dihydropyridine-3-carboxamido)-2-fluorophenoxy)picolinamide (30.8 g, 95%) as a pale yellow solid. 1H NMR (400 MHz, CD3OD) δ 8.34 (d, 1H, J=5.6 Hz), 7.94 (dd, 1H, J=12.4, 2.4 Hz), 7.80 (d, 1H, J=8 Hz), 7.48-7.46 (m, 3H), 7.31-7.28 (m, 3H), 6.86 (d, 1H, J=5.6 Hz), 6.61 (d, 1H, J=7.2 Hz), 4.34 (q, 2H, J=7.2 Hz), 1.45 (t, 3H, J=7.2 Hz); MS (ESI+) m/z 541.11 (M+H)+.
