실험 절차

A reaction mixture of 5-amino-quinoline-8-carbonitrile (1000.00 mg; 4.29 mmol; 1.00 eq.) in sulfuric acid (5.00 ml; 93.80 mmol; 21.86 eq.) was stirred at 100° C. for 1 h. The reaction mixture was then cooled, poured into ice and neutralized with 2N sodium hydroxide to PH=9. The precipitate was filtered, washed with water and dried to afford 5-aminoquinoline-8-carboxamide (800 mg, yield 74.3%).
