Reaction Steps

A mixture of phosphorus oxybromide (1.59 g, 5.55 mmol) and 8-bromo-2(1H)-quinolinone (0.250 g, 1.11 mmol) was heated at 125° C. for 2 h before being poured onto ice. The resulting precipitate was filtered and crystallized from MeOH to give 2,8-dibromo-quinoline (0.2 g, 64%) as colorless prisms. MS (ESI, pos. ion) m/z: 287.8 (M+1).
