Reaction Steps
To a sealed tube, under nitrogen was added 3-bromo-2-(4-chlorophenoxy)-pyridine (7 g, 25 mmol), 2-methylpyridin-4-ylboronic acid (3.4 g, 25 mmol), sodium carbonate (7.8 g, 74 mmol), S-phos (1 g, 2.5 mmol), Pd2(dba)3 (1.1 g, 1.2 mmol), and 180 mL of acetonitrile/water (5:1). The resulting mixture was heated to 75 C overnight. The reaction mixture was filtered to remove the solids and concentrated by rotovap. The residue was diluted with DCM and washed with brine. The organic layer was dried over Na2SO4 and concentrated. The solid and the residue was combined and purified by silica gel chromatography (0-10% MeOH/DCM) to afford 2-(4-chlorophenoxy)-3-(2-methylpyridin-4-yl)pyridine as solid. MS (ESI, pos. ion) m/z: 296.8 (M+1).
