Versuchsvorschrift

A solution of cyanogen bromide (5M, 1.44 mL, 7.22 mmol) was slowly added to a suspension of 3,4-diaminobenzoate (1.0 g, 6.02 mmol) in water (10 mL). The mixture was stirred at room temperature for 24 hours. An aqueous solution of Na2CO3 (10%) was added slowly until the product had precipitated as a brown solid (890 mg).
