Reference of 107867-51-6, 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 107867-51-6, name is 5-(Trifluoromethyl)pyridine-2,3-diamine. This compound has unique chemical properties. The synthetic route is as follows.
8-Aza-6-trifluoromethyl-1,4-dihydroquinoxaline-2,3-dione (52) A mixture of 51 (800 mg, 4.52 mmol) and diethyl oxalate (7.0 g, 47.9 mmol) was heated at 160 C. with stirring for 2 h (the mixture turned into a solution, then more and more precipitate was formed) and cooled to room temperature. The mixture was diluted with hexane (20 mL), filtered, washed with hexane (3*5 mL), and dried to give 997 mg (94%) of 52 as a yellow powder, mp >360 C. 1 H NMR (DMSO-d6), 7.625 (s, 1H), 8.441 (s, 1H), 12.120 (s, 1H), 12.703 (s, 1H). 19 F NMR (DMSO-d6), -131.225 ppm (The internal standard C6 F6: -162.9 ppm).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 107867-51-6, 5-(Trifluoromethyl)pyridine-2,3-diamine.
