Electric Literature of 131748-14-6, Adding some certain compound to certain chemical reactions, such as: 131748-14-6, name is 4-Chloro-(2-trifluoromethyl)pyridine,molecular formula is C6H3ClF3N, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 131748-14-6.
NaH (60% dispersion in mineral oil, 46 mg, .1.19 mmol) was added portionwise to a stirred solution of l-Boc-4-hydroxypiperidine (CAS: 109384-19-2; 200 mg, 0.99 mmol) in DMF (3 mL) in a sealed tube and under N2 at 0 C. The reaction mixture was stirred at 0 C for 30 min and a solution of 4-chloro-2-(trifluoromethyl)pyridine (CAS: 131748- 14-6; 271 mg, 1.49 mmol) in DMF (2 mL) was added dropwise at 0 C. The reaction mixture was stirred at 60 C for 48 h. The mixture was concentrated in vacuo. The residue was diluted with water and extracted with EtOAc. The organic layer was dried (Na2S04), filtered and the solvents were evaporated in vacuo. The crude product was purified by flash column chromatography (silica, EtOAc in DCM, gradient from 0:100 to 50:50). The desired fractions were collected and concentrated in vacuo to afford intermediate 104 (212 mg, 62%) as colorless oil which solidified to a white solid upon standing
According to the analysis of related databases, 131748-14-6, the application of this compound in the production field has become more and more popular.
