Procedure

To a solution of Methyl 3-(4-hydroxyphenyl)propanoate (0.5 g, 2.77 mmol) in dry DMF (10 ml) is added potassium carbonate (0.76 g, 5.55 mmol) followed by 4-(bromomethyl)pyridine hydrobromide (0.7 g, 2.77 mmol). The reaction mixture is stirred at room temperature overnight then poured into water (80 ml) and extracted with EtOAc (40 ml). The organic phase is washed with brine, dried (MgSO4) and the solvent removed in vacuo to yield a dark brown oil. Chromatography (SiO2, EtOAc) yields 3-[4-(Pyridin-4-ylmethoxy)-phenyl]-propionic acid methyl ester as a colourless oil; [M+H]+ 272.0
