Reaction Steps

3-Aminoquinoline (10 g, 69 mmol) was dissolved in 70 mL of conc. HCl in a 250 mL round bottomed flask and cooled to 0° C. Sodium nitrite (9.6 g, 139 mmol) in 20 mL water was added drop wise over 0.5 h while maintaining the reaction temperature between 0-5° C. After stirring for another 0.5 h, fluoroboric acid (20 mL) was added and the stirring continued for another 0.5 h. The solid was filtered and dried under vacuum to yield the title compound (15.2 g, 90%).
