The reaction mixture was heated to reflux for 13 h, diluted with EtOAc, washed with water (1×), brine (1×), dried over MgSO4, filtered through a pad (1.5 cm) of silica, and concentrated. The product 6-(bromomethyl)-3-methoxy-2-(4-(trifluoromethyl)phenyl)pyridine was used without further purification.
