Reaction Steps

In a mixture of 12 ml of pyridine and 35 ml of dioxane was suspended 4.55 g of 2-[3-(2-nitrophenoxy)phenoxy]propionamide and, then, 3.6 g of trifluoroacetic anhydride was added dropwise with ice-cooling and stirring. The mixture was then stirred at that temperature for 30 minutes and, following addition of ice-water, extracted with ether. The ether extract was washed with diluted hydrochloric acid and sodium hydrogen carbonate solution in that order, dried and concentrated to give 4.3 g of the title compound as a light yellow oil.
