Reaction Steps

60% oily sodium hydride (0.20 g, 5.0 mmol) was added to a solution of methyl (E)-α-hydroxy-2-(α-methyl-4-chlorobenzylideneaminooxy)phenylacetate (1.59 g, 4.6 mmol) and methyl iodide (1.95 g, 13.7 mmol) in N,N-dimethylformamide (15 ml) with stirring at 0° C. After 45 minutes, water was added, and the mixture was adjusted to pH 1 with 1N hydrochloric acid, extracted with ether, washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated, and the residue was purified by column chromatography on silica gel (n-hexane/methylene chloride=9/1) to give the desired compound methyl (E)-α-methoxy-2-(α-methyl-4-chlorobenzylideneaminooxy)phenylacetate (1.19 g, 72%) as an oil.
