Process for producing quinoline carboxyaldehyde derivative and intermediate thereof

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.
