Application of 20885-12-5, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 20885-12-5, name is 2-Chloro-6-fluoropyridine. This compound has unique chemical properties. The synthetic route is as follows.

To a solution of diisopropylamine (5.26 mL) in THF (70 mL) was added at -78C nBuLi 1.6M in hexanes (21.6 mL). The mixture was stirred at 0C for 45 min. 2-Chloro-6-fluoropyridine (3.5g) in THF (36 mL) was added dropwise at -78C over 1 h under nitrogen to the previous mixture and the reaction mixture was stirred at -78C for 1.5h. DMF (4.12 mL) was added dropwise over 1 h and the reaction mixture was stirred an additional 1 .5h. HCI 2M in diethylether (45 mL) was added slowly at -78C, water (30 mL) was added and the layers were separated. The aq. phase was extracted with EA and the combined org. layers were washed with sat. aq. NaCI, dried over Na2S04, filtrated off and evaporated in vacuo. The crude (4.4g of an orange solid) was used without purification in the next step. GC-MS (A): tR = 1 .55 min; [M+H]+: 159.80.

According to the analysis of related databases, 20885-12-5, the application of this compound in the production field has become more and more popular.
