In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 363-51-9, name is 2-Chloro-6-fluoroaniline belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Safety of 2-Chloro-6-fluoroaniline
A stirred solution of 9 4-hydroxy-2-methylsulfanyl-pyrimidine-5-carboxylic acid (5.70 g, 30.65 mmol, 1.0 eq) and 237 2-chloro-6-fluoro-aniline (4.50 g, 30.65 mmol, 1.0 eq) in 24 toluene (200 mL) was purged with nitrogen gas for 15 min. To the above solution 91 PCl3 (30 mL) was added. The reaction was heated at 100 C. for 72 h. Progress of reaction was monitored by LCMS. After completion of reaction, solvent was removed under reduced pressure, residue was diluted with a mixture of 238 diethyl ether: 30 MeOH (10:1) (100 mL) stirred for 15 min then filtered off. Solid was suspended in MeOH (20 mL), stirred for 5 min, filtered off and washed with MeOH (10 mL), and then dried under vacuum to obtain of 239 N-(2-chloro-6-fluoro-phenyl)-4-hydroxy-2-methylsulfanyl-pyrimidine-5-carboxamide (5.0 g, 52.8%). (0370) LCMS: 314 [M+1]+
The synthetic route of 363-51-9 has been constantly updated, and we look forward to future research findings.
