摘 要:3,4-二氢-7-(4-氯丁氧基)-2-(1H)-喹啉酮(DCHQ)是抗精神分裂症药物阿立哌唑的关键中间体。以间氨基苯酚为原料,经酰化,傅克烷基化,取代反应合成阿立哌唑中间体。其中3-氯-N-(3-羟基苯基)-丙酰胺(中间体1)收率95%,3,4-二氢-7-羟基-2-(1H)-喹啉酮(中间体2)收率63.2%,DCHQ收率92%。该工艺反应条件温和易于控制,反应时间短,收率高,适合工业化生产。 |

Abstract:3,4-Dihydro-7-(4-chlorobutoxy)-2(1H)-quinolinone (DCHQ) is a key intermediate of antischizophrinic aripiprazole. Target product was synthesized through acetylation, Friedel-Crafts alkylation and substitution reaction using aminophenol as the starting material. The yield of 3-chloro-N-(3-hydroxyphenyl)-propionamide (intermediate 1) was of 95%, 3,4-dihydro-7-hydroxy-2(1H)-quinolinone (intermediate 2) was of 63.2%, and the yield of DCHQ was of 92%. The reaction conditions were mild and easy to control with short-reaction time and high yield. This process is suitable for industrial manufacture. |
Key words:Aripiprazole; 3,4-dihydro-7-(4-chlorobutoxy)-2(1H)-quinolinone; antischizophrinic |
