What is the synthesis method of 3- (difluoromethyl) -5-fluoro-1-methyl-1H-pyrazole-4-formyl fluoride?

To prepare 3 - (diethylmethyl) - 5 - aldehyde - 1 - methyl - 1H - pyrrole - 4 - formamide, the following ancient method can be used.

First, with suitable starting materials, through the method of condensation. Take a compound containing active hydrogen, and a substance with a carbonyl group, and condensate the two in the presence of a basic catalyst. The basic catalyst can be selected from potassium hydroxide, sodium hydroxide, etc., in an alcohol solvent, heated at controlled temperature to promote the reaction. This step is intended to construct a preliminary carbon skeleton, so that the relevant groups are connected according to the design.

Next modified. The product obtained by condensation may require the introduction of specific functional groups. If an aldehyde group is to be obtained, it can be mildly oxidized. Choose such as manganese dioxide, chromium trioxide-pyridine complex isothermal and oxidizing agent, react at low temperature in an organic solvent such as dichloromethane, and precisely oxidize to aldehyde.

Then adjust the structure of the pyrrole ring. Cyclization reaction can be used to interact functional groups at appropriate positions in the molecule to form a pyrrole ring. Under acidic or basic conditions, according to the molecular structure characteristics, select suitable conditions. When acidic, p-toluenesulfonic acid, etc. can be selected; when alkaline, potassium carbonate, etc. may be a good choice. This step requires fine temperature control and time control to make the cyclization reaction smooth and highly selective. < Br >
Or by substitution reaction, methyl groups, formamide groups, etc. are introduced at specific positions in the pyrrole ring. Halogenated hydrocarbons are used as methyl sources, and nucleophilic substitution is carried out under alkaline conditions and with the assistance of phase transfer catalysts. The introduction of formamide groups can be reacted with corresponding acylating reagents, such as formamyl chloride, in the presence of organic alkali acid binding agents.

After each step of the reaction, it needs to be separated and purified. Extraction, distillation, column chromatography, etc., remove impurities to obtain pure products. The structure and purity of the product should be tested in detail at each step, and the method of spectral analysis such as nuclear magnetic resonance and infrared spectroscopy should ensure that the reaction proceeds as expected, and the product is the desired 3- (diethylmethyl) -5-aldehyde-1-methyl-1H-pyrrole-4-formamide.
