A solution of 2-phenyl-4-bromomethylbenzoic acid methyl ester (0.98 g) in DMF was then added and the reaction mixture was stirred until the bromide was consumed. The reaction mixture was partitioned between ethyl acetate and water. The organic phase was washed with brine, dried, and concentrated. The residue was purified by chromatography on silica gel (1:1 ethyl acetate-hexanes) to give [4-(3-pyridylmethyloxymethyl)-2-phenylbenzoic acid methyl ester (0.58 g).
