Some common heterocyclic compound, 93919-56-3, name is (4-(Trifluoromethoxy)phenyl)methanamine, molecular formula is C8H8F3NO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. COA of Formula: C8H8F3NO
In a round bottom flask fitted with magnetic stirrer and reflux condenser, 3- bromo-4-nitro-pyridine 1 -oxide (5.3 g, 24.25 mmol) and 4-(trifluoromethoxy)benzylamine (9.28 g, 48.55 mmol) were dissolved in propanol (50 ml) and heated to 90 C for 5 hours. Reaction mixture was allowed to cool overnight whilst stirring, with a solid crashing out of the reaction crude. This solid was filtered off, washed with I PA (2 x 10 ml) and dried in vacuo to afford the title compound (4.64 g, 58%). [00294] LCMS Method: 2, RT: 6.50 min, Ml: 330 [M+1] [00295] NMR, Method 1 : (DMSO) 8.82 (t 1 H), 8.05 (d 1 H), 7.94 (d 1 H), 7.52 (d 2H), 7.49 (dd 1 H), 7.36 (d 2H), 4.68 (d 2H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 93919-56-3, its application will become more common.
