PROCESS FOR PRODUCING QUINOLINECARBOXYALDEHYDE DERIVATIVE AND INTERMEDIATE

摘要

2-Cyclopropyl-4-(4'-fluorophenyl)quinoline-3- carboxyaldehyde useful as a material for pharmaceutical products, can be obtained by reacting 3-cyclopropyl-3- oxopropanenitrile with 2-amino-4'-fluorobenzophenone to obtain 2-cyclopropyl-4-(4'-fluorophenyl)quinoline-3- carbonitrile, and reducing it.
