Procedimiento

Combine 1-(2-bromo-4-fluoro-phenyl)-butane-1,4-diol (1 g, 3.8 mmol), silver (I)hexafluoroantimonate (131 mg, 0.4 mmol), platinum(II) chloride (40 mg, 0.2 mmol) in 1,2-dichloroethane (10 mL) in a pressure tube. Seal the tube and heat the mixture overnight at 110° C. Dilute the mixture with chloroform-IPA (3:1, 100 mL). Wash the organic phase with aqueous saturated sodium chloride and water. Dry the mixture over sodium sulfate. Concentrate the solution in vacuo. Purify by column chromatography (20% ethyl acetate in hexane) to give the title compound as a pale yellow oil (0.72 g, 77%).
