Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 26177-44-6, name is (4-Bromophenyl)methanamine hydrochloride, A new synthetic method of this compound is introduced below., HPLC of Formula: C7H9BrClN
A slightly yellow solution of 2,5-difluoro-4-(trifluoromethyl)aniline (10.0 ml; 76.708 mmol) in MeCN (90 ml) was treated with copper(ll) bromide (17.133 g; 76.708 mmol), and the green heterogeneous mixture was heated to 45C. A solution of tert-butyl nitrite (10.0 ml; 84.379 mmol) in MeCN (20 ml) was then added dropwise over 30 min., and the resulting mixture was further stirred at 45C for 2h30. The dark-green heterogeneous reaction mixture was allowed to cool to rt, and was directly purified by FC (DCM). After concentration to dryness under reduced pressure, the expected product 1-bromo-2,5-difluoro-4-trifluoromethyl- benzene was obtained as an orange oil (10.290 g; 51 %). LC-MS: tR = 1.07 min.; [M+H]+: no ionisation.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
