Purification by flash chromatography (silica gel, 4:1 hexane:ethyl acetate) afforded 1.9 g of 2-bromo-4,5-difluorobenzyl alcohol. To a solution of 1.9 g (8.4 mmol) of 2-bromo-4,5-difluorobenzyl alcohol in 30 mL of dichloromethane at 0° C. was added 3.4 g (10 mmol) of carbon tetrabromide and 2.7 g (10 mmol) of triphenylphosphine. The reaction was stirred for 2 h at this temperature, the solvent was removed in vacuo and the residue stirred with 100 mL of diethyl ether. The solution was filtered, concentrated in vacuo, and purified by flash chromatography (silica gel, 20:1 hexane:ethyl acetate) to afford 2-bromo-4,5-difluorobenzyl bromide contaminated with carbon tetrabromide which was used without further purification. Using the procedures outlined for the preparation of Intermediates 2-4, the benzyl bromide derivative was converted to the title compound. LC/MS 394 and 396 (M+1).

A solution of 2-(4-fluorobenzoyl)-3-methylpyridine (4.0 g) and sodium azide (6.7 g) in DMSO (80 ml) was stirred for 21 hours at 90° C. To the reaction mixture was added water, and the mixture was extracted with diethylether. The organic layer was washed with saturated brine, dried over magnesium sulfate and concentrated under reduced pressure, and a solution of the residue (3.90 g) in THF (40 ml) was added dropwise to a suspension of aluminum lithium hydride (1.24 g) in THF (40 ml) at 0° C. The mixture was stirred at room temperature for 3 hours, water (1.24 ml), 15% aqueous solution of sodium hydroxide (1.24 ml) and water (3.72 ml) were sequentially and slowly added dropwise to the solution at 0° C. The mixture was stirred temperature for 16 hours at room temperature, magnesium sulfate was added to the mixture, and the precipitates were removed by filtration (Celite). The reaction mixture was concentrated under reduced pressure, and the residue was recrystallized from ethyl acetate, to give (4-aminophenyl)(3-methylpyridin-2-yl)methanol (2.60 g) as pale yellow crystals.
