Procedure

To a solution of cyclopent-3-en-1-ol (CAS number 14320-38-8; 15 g, 178 mmol) in dry THF (357 ml) at 0° C. under nitrogen was added sodium hydride (60%, 9.27 g, 232 mmol). After fizzing had ceased, to this was then added drop wise 1-(chloromethyl)-4-methoxybenzene (CAS number 824-94-2; 31.4 ml, 232 mmol). The reaction was allowed to warm to room temperature and stirred for 17 hours then quenched by the addition of methanol and concentrated in vacuo. The residue was partitioned between ethyl acetate and water. The organics were dried over magnesium sulfate, filtered and concentrated in vacuo. The crude material was purified by column chromatography (silica, 0-50% DCM/petrol) to afford the title compound.
