With cooling, 0.25 g (0.0062 mol) of sodium hydride (60%) are added to a mixture of 2 g (0.0062 mol) of 2-[2-(5,6-difluoropyrimidin-4-yloxy)-phenyl]-2-methoxyimino-N-methyl-acetamide and 0.67 g (0.0062 mol) of 2-methylphenol in 20 ml of dimethylformamide, and the mixture is stirred at 25° C. for 12 hours. The reaction mixture is poured onto water and extracted with ethyl acetate, the organic phase is dried over sodium sulphate and the solvent is distilled off under reduced pressure. 1.5 g (58.9%) of 2-[2-(5-fluoro-6-o-tolyloxy-pyrimidin-4-yloxy)-phenyl]-2-methoxyimino-N-methyl-acetamide are obtained.
