PROCESS FOR PRODUCING QUINOLINECARBALDEHYDE

摘要

A novel process for producing a quinolinecarbaldehyde (IV) which comprises reacting an aminobenzophenone compound (I) with a beta-ketoaldehyde derivative (II) in the presence of an acid to obtain a quinolinecarbaldehyde derivative (III) and then hydrolyzing the quinolinecarbaldehyde derivative; and a process for producing a novel beta-ketoaldehyde derivative (II-1) which comprises reacting a metal alkoxide compound (V) with a diol derivative (VI) in the presence of an acid.
