67515-59-7, name is 4-Fluoro-3-(trifluoromethyl)benzonitrile, belongs to nitriles-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Safety of 4-Fluoro-3-(trifluoromethyl)benzonitrile
A mixture of 4-fluoro-3-trifluoromethylbenzonitrile (75 mg, 0.40 mmol), sodium sulfinate (44.5 mg, 0.44 mmol) in N,N-dimethylformamide (1.5 mL) was heated at 100 C. for 2 h. The reaction mixture was cooled to room temperature, quenched with water. The resulting white solid was collected via filtration, washed with cold water, dried in a vacuum oven to give 4-methanesulfonyl-3-trifluoromethyl-benzonitrile (90 mg, 90% yield). This benzonitrile was hydrogenated in 2N NH3 in methanol with 35 mg of Raney Ni under a hydrogen balloon for 2 h. The reaction mixture was filtered through a celite plug, washed with methanol, evaporated in vacuo to give the titled compound.
The synthetic route of 67515-59-7 has been constantly updated, and we look forward to future research findings.
