Electric Literature of 149793-69-1, These common heterocyclic compound, 149793-69-1, name is 3-Fluoro-5-(trifluoromethyl)benzonitrile, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: General procedure for nucleophilic substitution: A solution of 3-fluoro-5-trifluoromethyl-benzonitrile (1 eq) and the corresponding amine (3eq) in DMA was stirred at 145C during 3h. NaCl(aq) was added. The product was taken off into ethyl acetate. The organic layer was washed two times with water then dried over Na2S04 and evaporated under reduced pressure to give the intermediate compounds.
The synthetic route of 149793-69-1 has been constantly updated, and we look forward to future research findings.
