The resulting mixture was heated under reflux for 3 hours. Then, the reaction mixture was concentrated, ethyl acetate and water were added thereto, the solution obtained was extracted by liquid separation, and the organic phase was dried over magnesium sulfate. The dried organic phase was concentrated and bis(2-hexyldecyl)hydroxylamine as a by-product was removed using silica gel column chromatography to produce the objective compound. The product was a colorless liquid. Yield: 10.5 g (40.9%).
