primary 4-amino-2-aryl-3-(bromo/iodo)quinolines using 80% acetic acid under reflux. Tetrakis(triphenylphosphine)-palladium(O)-catalyzed Suzuki reaction of the 2-aryl-3-iodo-4-(triphenylphosphoranylideneamino)-quinolines with phenylboronic acid in dimethyl formamide in the presence of 2 M K2CO3 followed by hydrolysis of the incipient 2,3-diaryl-4-(triphenylphosphoranylideneamino)quinolines with 80% acetic
2-芳基-4-叠氮基-3-溴喹啉和2-芳基-4-叠氮基-3-碘喹啉与三苯基膦在回流四氢呋喃中的斯托丁格反应,得到了一系列的2-芳基-3-卤代-4-(三苯基磷酰亚氨基氨基)喹啉。 。后者随后在回流下使用80%的乙酸水解为相应的伯4-氨基-2-芳基-3-(溴/碘)喹啉。四(三苯膦) -钯(O)催化的铃木反应的2-芳基-3-碘-4-(triphenylphosphoranylideneamino)与苯基硼酸在-quinolines在2存在下二甲基甲酰胺中号ķ 2 CO 3,接着水解初始的2,3-二芳基-4-(三苯基正膦亚基氨基)喹啉与80%的乙酸得到4-氨基-2,3-二芳基喹啉。
