실험 절차

A 250 mL RB flask was charged with 1-(quinolin-6-yl)ethanone (3.82 g, 22.3 mmol) and 30% HBr/AcOH (45.0 ml). Bromine (1.14 ml, 22.1 mmol) was added slowly. This was stirred at room temperature for 4 hours, at which point full conversion to product (with a small amount of dibrominated side product) was observed. The reaction mixture was filtered and the solid was washed with Et2O to give 2-bromo-1-(quinolin-6-yl)ethanone hydrobromide (5.6359 g, 76.3% yield). The compound was used in the next step without further purification.
