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 99368-68-0, name is 6-Chloro-5-(trifluoromethyl)pyridin-3-amine. This compound has unique chemical properties. The synthetic route is as follows. Application In Synthesis of 6-Chloro-5-(trifluoromethyl)pyridin-3-amine
D. lambda/-(5-bromo-3-(trifluoromethyl)pyridin-2-yl)acetamideA mixture of 6-chloro-5-(trifluoromethyl)pyridin-3-amine (2.95 mmol, 0.58 g) and 30% HBr in acetic acid (6 ml) in a sealed tube was heated at 1000C overnight. The crude mixture was poured into ice water, the pH was set to10 with 2N aqueous NaOH and extracted withCHCI3.The solvent was removed under reduced pressure to afford 0.680 g (82% of yield) of the expected product.ESI/MS (m/e, %): 281.96 (100.0%), 283.96 (97.3%).
With the rapid development of chemical substances, we look forward to future research findings about 99368-68-0.
