Reaction Steps

Potassium carbonate (1.812 g, 13.11 mmol), methyl 2-chloroisonicotinate (3 g, 17.48 mmol), 2,4-dichlorophenylboronic acid (5.00 g, 26.23 mmol), PdCl2 (dppf) (0.380 g, 0.52 mmol), and MeOH (30.6 mL) were split in two 20 mL microwave vials and heated to 100° C. for 35 min in a single node microwave reactor. The reaction mixture was diluted with water and DCM, extracted with DCM and evaporated. Purified by automated flash chromatography using 5% EtOAc in heptane ->30% EtOAc over 15 CV at 280 nm. Methyl 2-(2,4-dichlorophenyl)isonicotinate (2.3 g, 47%) was isolated as a white solid. 1H NMR (400 MHz, cdcl3) δ 3.98 (s, 3H), 7.37 (dd, 1H), 7.53 (d, 1H), 7.57 (d, 1H), 7.86 (dd, 1H), 8.20 (s, 1H), 8.87 (d, 1H).
