• 製造方法

  2-Bromo-4-tert-butylaniline (7.41 g, 32.5 mmol), phloroglucinol (1.07 g, 8.5 mmol) and hydrochloric acid (37%, 0.5 mL) were added in a 100 mL flask. The flask was heated in an oil bath at 120℃ for 4 hours. After cooling down to room temperature, ethanol (20 mL) was added to the flask and the solid was crashed. The suspension was filter off and the solid was further washed with ethanol (40 mL) to give 8-bromo-6-tert-butylquinoline as colourless powder (5.46 g, 7.2 mmol, 85%). m.p. 230℃.
