3-Chloro-2-fluoro-pyridine - Reference Information
| Application | 3-chloro-2-fluoropyridine is an organic intermediate, it can be obtained from 2-nitro-3-chloropyridine or 2, 3-dichloropyridine by fluoro in one step. 3-chloro-2-fluoropyridine can be used for the preparation of 3-chloro-2 hydrazopyridine. 3-chloro-2-hydrazinopyridine is an important intermediate for the synthesis of a new type of receiver insecticide, chlorfenamide and cyanuramide. |
| preparation | cesium fluoride (2.053g,13.51 mmol) was added to 2, 3-dichloropyridine (1.00g,6.76 mmol) in dimethyl sulfoxide (33.8 ml). The mixture was stirred at 110°C for 20 h in air. The mixture was quenched with water at room temperature. The reaction mixture was extracted with EtOAc. The organic layer was separated. The organic layer was washed with water and brine. The organic layer was dried over anhydrous sodium sulfate. The organic layer was concentrated in vacuo. The residue was purified by column chromatography (silica gel, eluting with ethyl acetate in hexane) to give 3-chloro-2-fluoropyridine. |
