Versuchsvorschrift

3-Nitro-4-phenoxy-5-sulphamyl-benzoyl chloride (4 g) was added in portions to liquid ammonia (40 ml). Then excess of ammonia was distilled off, and the residue was triturated with water (50 ml). The precipitated 3-nitro-4-phenoxy-5-sulphamyl-benzamide was isolated by filtration and recrystallized twice from aqueous ethanol. After drying in vacuo, the compound was obtained with a melting point of 255°-256°C.
