    Abstract: Process for the preparation of 3-methylquinoline-8-carboxylic acid I and its derivatives by reacting o-toluidine II or its derivatives with methacrolein III in the presence of iodine or an iodine compound, in 70-90% by weight sulphuric acid, and oxidation of the resulting 3,8-dimethylquinoline IV or its derivatives with nitric acid in a solution of sulphuric acid in the presence of vanadium ions, characterised in that, in a first step, the by-products of the reaction are decomposed by oxidation in the reaction solution of 3,8-dimethylquinoline IV in sulphuric acid, the resulting 3,8-dimethylquinoline solution is concentrated by distillation, and subsequently the 3,8-dimethylquinoline is oxidised in situ with nitric acid to give 3-methylquinolinecarboxylic acid.
