Reaction Steps

To a solution of 3-n-butylamino-4-phenoxy-5-sulfamylbenzaldehyde (10 g; prepared as in Example 93) in hot methanol (100 ml) a solution of hydroxylamine hydrochloride (10 g) and ammonium acetate (10 g) in water (25 ml) is added, and the mixture is left for 3 days. Water (500 ml) is then added, and the resulting precipitate is collected by filtration, washed with water and dried in air. After recrystallization from a mixture of ethanol and 2-methoxyethanol, 3-n-butylamino-4-phenoxy-5-sulfamylbenzaldoxime is obtained with a melting point of 226°-228° C.
