Versuchsvorschrift
To a stirred solution of 3-aminobenzamide (Aldrich Chemical Co.) (0.476 g, 3.50 mmol) in ethyl acetate (50 ml) at ambient temperature was added 1.208 g of 3-chloroperoxybenzoic acid (commercial grade, 50-60% purity, Aldrich), whereupon the solution turned green. After 10 minutes the mixture was extracted with 0.14M aqueous sodium bicarbonate (58 ml), washed with three successive 40-ml portions of water, dried over sodium sulfate, then reduced in volume to 20 mL by rotary evaporation and placed in the freezer (-20° C.), whereupon the product slowly deposited as a light yellow solid during a period of 72 hours (0.180 g, 34% yield).
