What are the synthesis methods of 3- [ (4-bromo-2,6-difluorobenzyl) oxy] -5- [3- [4- (pyrrolidine-1-yl) butyl] ureyl] isothiazole-4-formamide?

To prepare 4-ethylpyridine, the following methods can be used:
First, use 3- [ (4-cyanogen-2,6-diethylamino) carbonyl] -5- [3- [4- (piperidin-1-yl) butyl] aminoformyl] isonicotinamide as raw material. First dissolve the raw material in a suitable solvent, such as dichloromethane, N, N-dimethylformamide, etc. Then, specific reagents are added to the reaction system, according to the needs of the reaction process, or basic reagents, such as sodium hydroxide, potassium hydroxide, etc., are added to adjust the pH of the reaction and promote the reaction to generate 4-ethylpyridine. Or add catalytically active substances, such as some transition metal catalysts and their ligands, to speed up the reaction rate. At the same time, the temperature and time of the reaction are precisely controlled. The temperature may be between 50 ° C and 150 ° C, and the time may be 12 hours to 48 hours. The reaction process is monitored by means of TLC (thin layer chromatography) and HPLC (high performance liquid chromatography). After the reaction is completed, the products are separated and purified by extraction, column chromatography and other methods.
Second, other suitable starting materials can be selected. For example, take a compound containing a pyridine ring with modifiable groups as the starting point, and use common reactions in organic synthesis, such as nucleophilic substitution reactions, electrophilic substitution reactions, etc. If the starting pyridine ring has a halogen atom, it can react with ethyl-containing nucleophilic reagents under appropriate conditions. During the reaction, choose a suitable base, such as potassium carbonate, sodium carbonate, etc., to promote the activity of the nucleophilic reagents. At the same time, choose a solvent that can dissolve the reactants without interfering with the reaction, such as acetonitrile, toluene, etc. Control the reaction temperature at room temperature to about 100 ° C. By monitoring the reaction process, stop the reaction in a timely manner, and then perform regular separation and purification operations to obtain pure 4-ethylpyridine.
Third, a multi-step reaction can also be considered to construct a pyridine ring and introduce ethyl. For example, the pyridine ring structure is first constructed by condensation and cyclization of compounds containing carbonyl and amino groups, and then ethyl is introduced by alkylation reaction. In the alkylation process, select suitable alkylation reagents, such as halogenated ethane, and select suitable catalysts and reaction conditions to achieve efficient and highly selective reactions, and finally separate and purify the target product 4-ethylpyridine.
