Reference of 1186050-58-7, A common heterocyclic compound, 1186050-58-7, name is 2-Fluoro-6-(2H-1,2,3-triazol-2-yl)benzoic acid, molecular formula is C9H6FN3O2, 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.
A mixture of [6-(hexahydro-pyrrolo[3,4-c]pyrrol-2-yl)-2-trifluoromethyl-pyrimidin- 4-yl]-dimethyl-amine (50 mg, 0.17 mmol), 2-fluoro-6-[1 ,2,3]triazol-2-yl-benzoic acid (37.8 mg, 0.18 mmol), HATU (94.6 mg, 0.25 mmol) and DIPEA (0.09 mL, 0.50 mmol) in DMF (4.0 mL) was stirred at room temperature for 30 minutes. The reaction mixture was diluted with ethyl acetate (60.0 mL) and washed with water (2 X 100 mL). The organic phase was dried (Na2SO ), filtered and concentrated to dryness. The crude product was purified using Agilent HPLC (Basic system) to yield pure title compound (19.0 mg, 23.4 %). MS (ESI) mass calcd. for C22H22F4N8O, 490.46; m/z found [M+H]+. 1 H NMR (CDCI3): 7.89-7.79 (m, 2H), 7.74 (s, 1 H), 7.55-7.37 (m, 1 H), 7.21 -7.05 (m, 1 H), 5.25-5.09 (m, 1 H), 4.25-3.51 (m, 6H), 3.50-2.95 (m, 10H).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
