Procedure
Sodium hydride (0.43 g, 10.8 mmol) is added portionwise to a solution of α-hydroxy-γ-butyrolactone (1 g, 9.8 mmol) in DMF (15 ml) at 0° C. under a nitrogen atmosphere. 2-Bromomethylbiphenyl (2.42 g, 9.8 mmol) is then rapidly added. The reaction medium is stirred for 2 hours at room temperature and is then treated by adding 1N hydrochloric acid solution (10 ml). The aqueous phase is extracted with ethyl acetate (2×20 ml) and the combined organic phases are washed with water (4×15 ml), dried over sodium sulphate, filtered and concentrated. After purification by flash chromatography (2/1 heptane/EtOAc), the expected compound is obtained in the form of a colourless oil (1.32 g, 50%).
