Application of 86770-80-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 86770-80-1, name is 3,3-Difluorocyclobutanecarbonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
3 ,3-difluoro- 1 -(4-(trifluoromethyl)pyridin-2-yl)cyclobutanecarbonitrile [1270] Example 125B and 2-fluoro-4-(trifluoromethyl)pyridine (0.900 mL, 7.39 mmol) were dissolved in toluene (2.4 mL), cooled to <5 C and added KHMDS (29.6 mL, 14.78 mmol) dropwise, allowed to warm slowly to room temperature and stirred for 90 minutes. The mixture was diluted with MTBE and washed with water (2x). The organic phase was dried (Na2S04), filtered, and concentrated. The residue was chromatographed on silica gel (0-25% EtOAc/hexanes) to provide Example 125C (1.22 g, 4.65 mmol, 63.0 % yield). XH NMR (300 MHz, DMSO-d6) ? 9.00 - 8.94 (m, 1H), 8.04 - 7.99 (m, 1H), 7.88 (ddd, J= 5.1, 1.6, 0.8 Hz, 1H), 3.68 - 3.48 (m, 5H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3,3-Difluorocyclobutanecarbonitrile, other downstream synthetic routes, hurry up and to see.
