3-fluoro-p-anisaldehyde (12.5 g, 81.1 mmol) was dissolved in 100 ml THF. Under N2 a solution of diisobutylalumium hydride (100 ml, 1M in THF) was added at 0° C. over 30 min. The reaction was stirred for 30 min and quenched with 250 ml 1N HCl solution. The resulting mixture was stirred for 15 min and filtered through a short column of Celite®. The product was extracted with ethyl acetate. The aqueous layer was extracted with ethyl acetate. The combined organic layer was dried with MgSO4, and concentrated to give a viscous oil in 11.6 g. This product was used without further purification. NMR spectra of the product were consistent for the proposed structure.
