Reaction Steps

A mixture of 4-fluoro-2-methyl-5-nitrophenol (4.69 g, 27 mmol), (prepared as described for the starting material in Example 8), benzyl bromide (3.59 ml, 30 mmol) and potassium carbonate (7.58 g, 55 mmol) in DMF (100 ml) was heated at 80° C. for 4 hours. The reaction mixture was allowed to cool and diluted with water and stirred for 15 minutes. The precipitated product was collected by filtration, washed with water and dried to give 5-benzyloxy-2-fluoro-4-methyl-1-nitrobenzene (6.4 g, 89%).
