To prepare N4- (4-methoxyphenyl) -2-nitrobenzene-1,4-dicarboxylic acid, the following ancient method can be used.
First take an appropriate amount of 4-methoxybenzaldehyde, place it in a clean reactor, use alcohol as a solvent, add a base as a catalyst, heat it at controlled temperature, and make it co-react with diethyl malonate. This step aims to obtain the corresponding cinnamate ester intermediates through Knoevenagel condensation reaction. During the reaction, it is necessary to closely observe and adjust the temperature and stirring rate depending on the reaction process to ensure a smooth reaction.
After obtaining the intermediate, move it to another reaction vessel and add a strong nitrifier, such as a mixed acid of concentrated nitric acid and concentrated sulfuric acid. Under low temperature and careful stirring, slowly add mixed acid dropwise to carry out nitrification reaction. This step must be strictly controlled to prevent excessive nitrification or other side reactions. After nitrification, nitro-containing cinnamate derivatives can be obtained.
Subsequently, the nitro-containing derivatives are treated with a strong alkali solution and heated for hydrolysis. In this process, the ester group is hydrolyzed to carboxyl groups to obtain compounds containing carboxyl groups and nitro groups. After hydrolysis, adjust the pH with acid to precipitate the product.
Then take the resulting product, add an appropriate amount of halogenated alkanes, such as iodomethane, and perform a methylation reaction in an alkaline environment with the help of a phase transfer catalyst to protect one of the carboxyl groups. This step can make the subsequent reaction more selective.
Then, the nitro group is reduced. Suitable reducing agents, such as iron filings and hydrochloric acid, or hydrogen and metal catalysts, can be used to convert the nitro group to an amino group. After reduction, the amino group is treated with an acylating agent to obtain the acylation intermediate of N4- (4-methoxyphenyl) -2-nitrobenzene-1,4-dicarboxylic acid.
Finally, the protecting group on the carboxyl group is removed by hydrolysis reaction to obtain N4- (4-methoxyphenyl) -2-nitrobenzene-1,4-dicarboxylic acid. After each step of the reaction, it needs to be separated and purified by methods such as extraction, recrystallization, column chromatography, etc., to remove impurities and maintain the purity of the product. All these methods are interconnected, and the preparation of this compound can only be achieved when careful and meticulous during operation.
