실험 절차
The mixture consisting of 7.7 g of ammonium acetate, 3.8 g of 10% palladium on charcoal, 0.025 mole (7.6 g) of 2,4-diethoxy-3,5-diaminochlorobenzene hydrochloride in 42 ml of ethanol containing 5 ml of water was heated to 70° C. with stirring. 7.5 g of triethylamine were added and then, 3.1 g of formic acid were added dropwise. After 20 additional minutes of heating at 80° C., the reaction mixture was filtered while hot. The filtrate was evaporated to dryness. Upon addition of ethyl acetate, the inorganic salts were precipitated and removed by filtration. 10 ml of a 7N alcoholic solution of hydrochloric acid were added to the filtrate which was dried over sodium sulphate. The expected product precipitated; it was recrystallized from a 6N hydrochloric acid solution.
