摘要:
以N-乙酰乙酰苯胺为原料,经溴化、环合制得4-溴甲基喹啉-2-酮(Ⅲ);由盐酸氨基丙二酸二乙酯经酰化制得4-苯甲酰胺基丙二酸二乙酯(Ⅳ);最后用4-溴甲基喹啉-2-酮(Ⅲ)和4-氯苯甲酰胺基丙二酸二乙酯(Ⅳ)经烃化反应合成瑞巴匹特羧乙酯(Ⅰ).结果表明:在n(Ⅳ)∶n(Ⅲ)∶n(乙醇钠)=1∶1∶1.2,回流反应2 h时,合成总收率63.81%(以N-乙酰乙酰苯胺计).
Abstract:
The diethyl-2-(4-chlorobenzoylamino)-2-(1,2-dihydro-2-oxo-4-quinolyl)malonate, an intermediate of ribamipide was synthesized from N-Acetoacetanilide as material.Firstly,4-(bromomethyl)-quinolin-2(1H)-one was obtained by the bromination and cyclization. Then,diethyl-2-(4-chlorobenzamido)malonate was obtained by the acylation of diethyl aminomalonate hydrochloride. Finally, diethyl-2-(4-chlorobenzoylamino)-2-(1,2-dihydro-2-oxo-4-quinolyl)malonate was prepared by alkylation of 4-(bromomethyl)-qui-nolin-2(1H)-one with diethyl-2-(4-chlorobenzamido)malonate, under the conditions which were as follows:the molar ratio of Ⅳ toⅢ to sodium alcoholate was 1∶1∶1.2,the refluxed time was 2 h. The total yield was 63.81%(with N-Acetoacetanilide as the material).
