Reaction Steps

A solution of methyl 4-formyl-2-methylbenzoate (1.3 g) in tetrahydrofuran (50 mL) was added dropwise to a solution of hydroxylamine hydrochloride (1.0 g), sodium acetate (1.2 g) in tetrahydrofuran (50 mL) and water (50 mL) under ice cooling, and after finishing the dropwise addition, the mixture was stirred for one hour at room temperature. The reaction mixture was diluted with water and then extracted with ethyl acetate, and the organic layer was dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure to obtain a crude product of methyl 4-[(hydroxyimino)methyl]-2-methylbenzoate (1.3 g).
