Synthesis

700871-86-9

700871-88-1

General procedure for the synthesis of 4,7-dibromoquinoline from compound (CAS: 700871-86-9): precursor compound 20 (3.15 g, 8.8 mmol) and lithium bromide (LiBr, 7.7 g, 88.5 mmol) were dissolved in 100 mL of acetonitrile (CH3CN). The reaction mixture was heated and stirred at 55 °C for 8 h under nitrogen protection. Upon completion of the reaction, the mixture was cooled to room temperature and concentrated under reduced pressure to a slurry. The crude product was diluted with ethyl acetate (EtOAc, 30 mL) and subsequently washed with saturated sodium bicarbonate (NaHCO3) solution. The organic phase was separated, extracted with saturated sodium chloride solution, dried over anhydrous sodium sulfate (Na2SO4), filtered and concentrated under reduced pressure to give the solid crude product. Purification by medium pressure liquid chromatography (MPLC) on a silica gel column with 25% ethyl acetate/hexane as eluent gave 1.9 g of white solid 4,7-dibromoquinoline in 75% yield. Mass Spectrometry (MS) ES+ m/e: 287.8 (M + 1).
