Reaction Steps

To a solution of 4-(4-Bromo-benzoyl)-benzoic acid ethyl ester (2.0 g, 6 mmol) in THF (20 mL) at 0° C. is added hexylmagnesium bromide (2M, 3.3 mL). After stirring at room temperature for 2 hours, it is quenched with saturated ammonium chloride, extracted with EtOAc. The organic is concentrated and purified by column chromatography to give 4-[1-(4-Bromo-phenyl)-1-hydroxy-heptyl]-benzoic acid ethyl ester (0.48 g, 19%), which is taken into methanol (2 mL), treated with sodium hydroxide (5N aqueous, 1 mL) for 3 h at room temperature. The mixture is concentrated, diluted with ethyl acetate, acidified with 5 N HCl (1.1 mL), extracted with ethyl acetate. The organic layers are dried and concentrated giving to afford the titled compound (0.47 g).
