1H-2-Phenylpyrrolo[3,2-c]quinoline (1a) is made by thermal cyclization of quinol-4-yl hydrazone. Subsequent substitution of the C-3 hydrogen atom of the pyrrole ring of 1a with chlorine and a formyl group is easily achieved by reacting 1a with trichloroacetyl chloride and phosphorus oxychloride in DMF, respectively.
1 H -2-苯基吡咯并[3,2- c ]喹啉(1a)是通过对喹啉-4-基yl进行热环化而制得的。通过使1a分别与三氯乙酰氯和氯氧化磷在DMF中反应,可以容易地用氯和甲酰基随后取代1a的吡咯环的C-3氢原子。
