Process for producing quinoline compound

摘要

By a production method of a quinoline compound represented by the formula (I), which comprises reacting quinolinecarbaldehyde represented by the formula (II) with an imine compound represented by the formula (III) and then subjecting the resulting compound to hydrolysis, a quinoline compound useful as a synthetic intermediate for pharmaceutical agents, agricultural chemicals and the like can be efficiently and industrially advantageously produced in a short step using a starting material industrially easily available and easy to handle: wherein R¹, R², R³, R⁴, R⁵, R⁶ and R⁷ are as defined in the description.
