These common heterocyclic compound, 93919-56-3, name is (4-(Trifluoromethoxy)phenyl)methanamine, its 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. Recommanded Product: 93919-56-3
A solution of the ethyl 3-(3,5-dibromo-4-hydroxyphenyl)-1,2,4-oxadiazole-5-carboxylate (78 mg, 0.2 mmol) plus 4-trifluoromethoxybenzyl amine (57 mg, 0.3 mmol) in ethanol (3 mL) was refluxed for 6 hours. The resulting solution was evaporated in vacuo and the residue was dissolved in ethyl acetate (2.5 mL) and washed with 1 N hydrochloric acid (2 mL), then water (2 mL). The organic layer was evaporated to dryness in vacuo and purified by preparative HPLC to give the title compound (57 mg, 53%) as a colourless powder. 1H NMR delta (ppm) (DMSO-d6): 4.55 (2H, d), 7.38 (2H, d), 7.51 (2H, d), 10.07 (1H, t), 10.95 (1H, s, br). LCMS (10 cm_apci_formic) tR4.14 min; m/z 534/536/538 [M-H]-.
The synthetic route of (4-(Trifluoromethoxy)phenyl)methanamine has been constantly updated, and we look forward to future research findings.
