EXAMPLE 4 This example illustrates the preparation of 4-bromo-5-nitro-isoquinoline having the formula: SPC9 4-bromo-isoquinoline (10.4 g) was dissolved in concentrated sulphuric acid (50 ml) and the solution was cooled to approximately 5¡ãC. A solution of potassium nitrate (8.6 g) in concentrated sulphuric acid (50 ml) was then added in dropwise fashion to maintain the temperature of the reaction mixture in the range 0¡ãC to 10¡ãC. After the addition was completed the reaction mixture was poured onto a mixture of ice (300 g) and water (300 ml), and ammonia was then slowly added until the mixture became alkaline. The reaction mixture was then filtered, and the yellow material thus isolated was washed with water and allowed to dry, to provide 9.0 g of 4-bromo-5-isoquinoline, melting at 177¡ã – 178¡ãC.
1532-97-4 4-Bromoisoquinoline 73743, aisoquinoline compound, is more and more widely used in various.
