Procedure

Dissolve 2-fluoro-5-iodobenzaldehyde, (prepared essentially as described in Tet. Lett., 33, 7499, (1992)), (6.54 g, 26.1 mmol) in 4:1 tetrahydrofuran:methanol (200 mL) and treat with sodium borohydride (1.98 g, 52.3 mmol) and stir overnight. Concentrate the reaction mixture, then partition between ethyl acetate and water. Wash the organic layer with an aqueous saturated solution of sodium chloride, dry (sodium sulfate), filter, and concentrate. Purify the crude oil by silica gel chromatography, eluting with 85:15 hexanes:ethyl acetate, to give the title compound as a white crystalline solid (5.8 g, 88%).
