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
