Reaction Steps

N-Bromosuccinimide (1.2 equiv., 0.358 mmol, 0.061 g) was added to a solution of 1 (1.0 equiv., 0.295 mmol, 0.105 g) in DMF (3 ml). The reaction mixture was stirred at room temperature for 4 h. Water was added, the resulting precipitate was isolated by filtration and washed with water, isopropanol and isopropyl ether successively to give 3-bromo-6-(4-nitrophenyl)-pyrido[2′,1′:2,3]imidazo[4,5-c]isoquinolin-5(6H)-one (101) (0.050 g, yield=36%, purity (LC)=93%).
