Reaction Steps

To a de-gassed mixture of 2-chloro-3-(trifluoromethyl)-pyridine (70.1 mmol), p-tolylboronic acid (70.6 mmol), and 2M Na2CO3 (175.0 mmol), in DME (200 mL) under nitrogen add Pd(PPh3)4 (2.8 mmol). Stir the mixture at 80° C. for overnight, concentrate, extract with EtOAc. Dry over Na2SO4, concentrate under vacuum, pass a silica gel pad to give 2-p-tolyl-3-trifluoromethyl-pyridine.
