Versuchsvorschrift

Add 11 g of 4-bromoisoquinoline to 45 ml of sulphuric acid, followed, dropwise, by a solution of 9.1 g of potassium nitrate in 45 ml of sulphuric acid whilst cooling in an ice-bath. The reaction mixture is stirred at room temperature for 2 hours 30, before being poured onto ice. After the resulting solution has been rendered basic with ammonium hydroxide, the crystals are filtered off, washed and dried to yield the expected product.
