Participants

Reaction Steps

To 5 ml of a methanol solution containing 0.98 g (3.7 mmol) of the 1-(2-n-butoxyimino-2-cyano-1-ethoxyiminoethyl)-1H-1,2,4-triazole produced in Example 17 were added, at room temperature, 60 mg (0.19 mmol) of tetrabutylammonium bromide, 55 mg (0.40 mmol) of potassium carbonate and 1.7 g (15 mmol) of an aqueous 30 wt. % hydrogen peroxide solution, followed by stirring for 10 hours. To the reaction mixture was added sodium dithiosulfate, followed by stirring for 10 minutes. The reaction mixture was concentrated under reduced pressure. The resulting crystal was washed with an aqueous citric acid solution, cold water and isopropyl ether in this order, to obtain 0.64 g (yield: 61%) of a title compound.
