The crude oil was dissolved in dioxane (100 mL) and treated with 2-fluoropyridin-3-ylboronic acid (3.47 g, 24.63 mmol), potassium phosphate (5.23 g, 24.63 mmol), and 1,1-bis[(di-t-butyl-p-methylaminophenyl]palladium(II) chloride (0.25 g, 0.35 mmol). Water (10 mL) was added and the reaction heated to 90° C. for 10 min. Water (300 mL) and ethyl acetate (200 mL) were added and the phases mixed and separated. The organic was dried with magnesium sulfate and evaporated to dryness under reduced pressure. Purification of the crude material using silica chromatography (hexane to ethyl acetate gradient) gave (2-fluoro-5-(2-fluoropyridin-3-yl)phenyl)methanol (2.54 g, 47%). MS m/z=222.1 [M+H]+. Calculated for C12H9F2NO: 221.05.
