Reaction Steps

A solution of hydroxylamine hydrochloride (2.73 g, 39.3 mmol) in water (35 ml) was treated with sodium acetate (2.74 g, 33.4 mmol) followed by a solution of 3,4-dichlorobenzaldehyde (4.0 g, 22.8 mmol) in tetrahydrofuran (15 ml) and the resulting mixture was stirred at 22° C. for 2 h. The reaction mixture was then diluted with ether (250 ml), washed with water, brine and dried over anhydrous magnesium sulphate. Evaporation of the solvent gave 4.3 g of 3,4-dichlorobenzaldehyde oxime as a white solid.
