Synthetic Route of 93919-56-3,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.
To a solution of lithium 3-[(2-Dimethylamino-ethyl)-methyl-amino]-lH-indazole- 6-carboxylate (77mg, 0.29 mmol) in anhydrous DMF (5mL) was added EDC (140mg, 0.73mmol) and etaOBt (47mg, 0.35mmol). The mixture was stirred for 10 min. then Et3N (0.16mL, 0.1.16mmol) and 4-trifluoromethoxybenzylamine (0.049mL, 0.32 mmol) were added. The mixture was heated at 50 0C for 15 hr. The mixture was allowed to cool, diluted with ethyl acetate (50 mL) and washed with aqueous sodium bicarbonate (25 mL). The aqueous layer was extracted with ethyl acetate (50 mL) and the combined organic layers were dried over anhydrous sodium sulfate and concentrated in vacuo. Chromatography on silica yielded the title compound (37mg, 29%). m/z (M+eta) = 436.45.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route (4-(Trifluoromethoxy)phenyl)methanamine, its application will become more common.
