Title:
METHOD FOR PRODUCING QUINOLINECARBOXALDEHYDE DERIVATIVE
Document Type and Number:
Japanese Patent JP2002241367
Kind Code:
A
Abstract:
To provide an industrially advantageous method for producing a quinolinecarboxaldehyde derivative with which the quinolinecarboxaldehyde derivative can be produced by a simple method with a high yield.
This method for producing the quinolinecarboxaldehyde derivative is characterized by comprising (A) a cyclization reaction process of reacting β-ketonitrile with o-acylaniline in the presence of an acid to obtain a quinolinecarbonitrile derivative and (B) a reduction reaction process or then reducing the quinolinecarbonitrile derivative to obtain the quinolinecarboxaldehyde derivative.
