What are the preparation methods of Ethyl 5-fluoro-3-iodo-1h-indole-2-carboxylate?
The preparation of Ethyl 5-fluoro-3-iodo-1H-indole-2-carboxylate (5-fluoro-3-iodo-1H-indole-2-carboxylate) follows the path of organic synthesis.
First, it can be started from a suitable indole derivative. First, take the indole containing the corresponding substituent and introduce the iodine atom at its 3 position. In this step, an iodine substitution reagent, such as iodine elemental (I _ 2), can be used in combination with a suitable oxidizing agent. Under suitable reaction conditions, the indole 3 position undergoes an electrophilic substitution reaction to introduce the iodine atom. Common oxidizing agents such as hydrogen peroxide (H2O) or potassium persulfate (K2O), etc., in organic solvents such as acetonitrile or dichloromethane, the temperature and reaction time are controlled to achieve the preparation of 3-iodoindole.
Then, fluorine atoms are introduced at the 5th position. Or a nucleophilic substitution strategy can be adopted. If there are suitable leaving groups at the 5th position, such as halogen atoms (non-fluorine) or sulfonate groups, nucleophilic fluorinated reagents can be selected, such as potassium fluoride (KF), tetrabutylammonium fluoride (TBAF), etc. In the presence of a phase transfer catalyst, in a suitable polar organic solvent, such as N, N-dimethylformamide (DMF) or dimethyl sulfoxide (DMSO), the reaction is heated to replace the 5-position leaving group with a fluorine atom to obtain a 5-fluoro-3-iodine-indole derivative.
Finally, the esterification reaction of the carboxyl group is carried out to obtain the target product. The resulting 5-fluoro-3-iodine-1H-indole-2-carboxylic acid is reacted with ethanol under acid catalysis. The commonly used acids are concentrated sulfuric acid or p-toluenesulfonic acid. Under reflux conditions, the reaction was carried out for a period of time, and the water generated by the reaction was removed through a water separator to promote the reaction to proceed in the direction of ester formation, so as to obtain Ethyl 5-fluoro-3-iodo-1H-indole-2-carboxylate.
There are other methods to follow, such as using substituted aromatics containing fluorine and iodine as starting materials to construct indole rings through multi-step cyclization reaction, and then esterification. This path may involve various organic reactions such as Fu-gram reaction and cyclization condensation. However, the reaction conditions need to be carefully adjusted to achieve the ideal yield and selectivity.
