Komponenten

Versuchsvorschrift

A mixture of 3-[(4-methoxybenzyl)oxy]pyridin-4(1H)-one (7.30 g, 31.6 mmol), 2-fluoro-4-iodopyridine (10.56 g, 47.35 mmol), and K2C03 (10.9 g, 79 mmol) in DMSO (80 mL) was heated at 80° C. overnight. The reaction mixture was cooled to room temperature, diluted with EtOAc, washed with water and brine, dried (Na2S04), filtered and concentrated. The residue was washed with EtOAc and filtered, and the collected solid dried to give 4′-iodo-3-[(4-methoxybenzyl)oxy]-4H-1,2′-bipyridin-4-one. 1H-NMR (DMSO, 400 MHz) (5 8.41 (dd, J=8.0, 2.4 Hz, 1H), 8.30 (s, 1H), 8.20 (m, 2H), 7.81 (dd, J−4.0, 0.8 Hz, 1H), 7.35 (d, J=8.4 Hz, 2H), 6.92 (d, J=8.4 Hz, 2H), 6.28 (d, J=7.6 Hz, 1H), 4.96 (s, 2H), 3.72 (s, 3H). MS (M+H)+ 435.1.
