functional derivatives, such as the acid chloride or anhydride, in the presence of a dehydration or dehydrohalogena~ tion agent. Phosphorus oxychloride, thionyl chloride, phosphorus trichloride, phosphorus pentachloride, and the like can be used as dehydrating agents. As dehydrohalogenation agents, excess 4-methylaminoantipyrene, tertiary amines (triethylamine, pyridine) or in-
化合物 (I) 的合成是通过 4-甲基-氨基芘或其盐酸盐与 3,4,5-三甲氧基苯甲酸或其官能衍生物如酰氯或酸酐在脱水或脱卤化氢~剂。可以使用三氯氧化磷、亚硫酰氯、三氯化磷、五氯化磷等作为脱水剂。作为脱卤化氢剂,过量的 4-甲基氨基安替芘、叔胺(三乙胺、吡啶)或在-
