Reaction Steps
To a stirred solution of (4-Bromo-2-methyl-phenyl)-methanol (as obtained in preparation 25) (4.58 g, 22.8 mmol) in CH2Cl2 (50 ml) is added, under Argon and at RT, carbon tetrabromide (9.27 g, 27.4 mmol) followed by triphenylphosphine (7.25 g, 27.4 mmol). The mixture is stirred overnight and then concentrated in vacuo. The crude residue is then purified by chromatography (silicagel, hexane:EtOAc 25:1) to afford the title compound as a clear oil.
