Reaction Steps

To (E)-2-[2-(biphenyl-4-yloxymethyl)phenyl]-2-hydroxyimino-N-methylacetamide(9.73 g, 0.027 mol), added were dry acetone (100 ml), potassium carbonate (11.20 g, 0.081 mol) and dimethylsulfate (6.81 g, 0.054 mol), and the reaction mixture was stirred overnight at room temperature. Then, undissolved materials were removed therefrom and the remaining mixture was concentrated under reduced pressure. The residue was purified by silica gel chromatography (ethyl acetate/n-hexane) to give (E)-2-[2-(biphenyl-4-yloxymethyl)phenyl]-2-methoxyimino-N-methylacetamide (9.85 g; yield, 97.4%) as colorless crystals.
