Reaction Conditions

Reaction Steps

Toluene (3 ml) and conc. hydrochloric acid (0.61 g, 6 mmol) were added to 2-[2-(2,5-dimethylphenoxymethyl)phenyl]-2-methoxyimino-N-methylacetamide (0.98 g, E/Z=75/25), and the mixture was stirred at 80° C. for 2 hours. After completion of the reaction, water (150 ml) was added. The mixture was extracted with methylene chloride (50 ml) twice, dried over anhydrous magnesium sulfate and concentrated under reduced pressure to give crystals (1.01 g, E/Z=95/5). The crystals were recrystallized from toluene to give (E)-2-[2-(2,5-dimethylphenoxymethyl)-phenyl]-2-methoxyimino-N-methylacetamide (0.72 .g, Yield 71.5%) as colorless crystals.
