Application of 1159512-64-7,Some common heterocyclic compound, 1159512-64-7, name is 2-Fluoro-3-(trifluoromethoxy)aniline, molecular formula is C7H5F4NO, 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.
To a solution of (2S,4R)-1-(tert-butoxycarbonyl)-4-fluoropyrrolidine-2-carboxylic acid (1 equiv) in DMF (10 vol) at 0 C. under nitrogen atmosphere was added 2-fluoro-3-(trifluoromethoxy)aniline (1.2 equiv), HBTU (1.5 equiv) and DIPEA (3 equiv). The reaction mixture was stirred at room temperature for 12 h. After completion of the reaction, the reaction mixture was quenched with water. The resulting mixture was extracted with DCM. The organic layer was washed with brine, dried over anhydrous Na2SO4, filtered and then concentrated. The residue was purified by column chromatography on silica gel using DCM/MeOH to give compound 1239.
The synthetic route of 1159512-64-7 has been constantly updated, and we look forward to future research findings.
