Reaction Steps

To a solution of 2.3 g of 6-(4-fluorobenzyloxy)-3-pyridine methanol in 20 ml of N,N-dimethylformamide was added under stirring at 0° C. 0.5 g of 55% sodium hydride (in mineral oil). After stirring for 30 minutes at room temperature, thereto was added dropwise a solution of 2.0 g of 2-t-butyl-5-chloro-4-methyl-3(2H)-pyridazinone in 5 ml of N,N-dimethylformamide. The reaction mixture was stirred at room temperature for additional 8 hours, poured into 50 ml of ice water and extracted twice with 50 ml of benzene. The organic layer was washed with water, dried over anhydrous sodium sulfate and then freed of solvent by distillation under reduced pressure to give 3.8 g of a crude product. The crude product was separated and purified through thin layer chromatography (on silica gel; benzene) to obtain 2.5 g of 2-t-butyl-5-[{6-(4-fluorobenzyloxy)-3-pyridyl}-methyloxy]-4-methyl-3(2H)-pyridazinone as an oil.
