A mixture of 5-(2-chloro-4-trifluoromethylphenoxy)benzo-2,1,3-oxadiazole N-oxide (20.0 g, 61.0 mmol) and hydroxylamine (4.0 g, 120.00 mmol) in 50 ml of methanol is stirred at 45° for 18 hours. The reaction is cooled to RT and 10 ml of water is added. The resulting white solid which precipitates is collected and dried to give 4-(2-chloro-4-trifluoromethylphenoxy)-ortho-benzoquinone dioxime.
