Abstract
A series of l-aryl-1H-pyrazolo[4,3-c]quinolines and 2-aryl-2H-pyrazolo [4,3-c]quinolines are prepared by reacting 3-acyl-4-chloroquinolines i n ethanol or 3-acyl-4(1H)-quinolone in acetic acid with appropriate hy drazines as possible anti-ulcer agents. A regiospecific synthesis of l -aryl-1H-pyrazolo[4,3-c]quinolines is also achieved. The central pyrid ine ring could be easily reduced by catalytic hydrogenation.
