To a mixture of 3-fluorobenzyl alcohol (7.88 g, 62.5 mmol), Aliquot 336 (8.08 g, 20.0 mmol), potassium hydroxide (3.51 g, 62.5 mmol) and water (40 mL) were added toluene (80 mL) and 1,2-dichloro-4-nitrobenzene (10.0 g, 52.1 mmol). The mixture was heated to 60° C. overnight with vigorous stirring. The mixture was diluted with ethyl acetate and washed with water. The organic layer was dried over sodium sulfate, and the solvent was removed in vacuo. The residue was triturated with hot petroleum ether and tert-butyl methyl ether to yield 9.20 g (63%) of the title compound.
