Synthetic Route of 10057-46-2, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 10057-46-2, name is 2-Amino-5-(trifluoromethyl)benzoimidazole, This compound has unique chemical properties. The synthetic route is as follows.
2-(2,3-Dih drobenzofuran-5-yl)-N-(5-(trifluoromethyl)-lH-bcnzo[]imida7.oI-2- yl)thiazole-4-carboxamide (5) To a solution of 2-(2,3-dihydro-l-benzofuran-5-yl)-l,3-thiazole~4-carboxylic acid (1.00 g. 4.04 mmol) in 20 ml NN-dimethylformamide, were added 5-(trifluoromethyl)-lH- benzo[7Jimidazol-2-amine (895 mg, 4.45 mmol), 2-(lH-benzotriazole-l-yl)-l,l,3,3- tetramethyluronium hexafluorophosphate (HBTU) (1.53 g, 4.04 mmol), 4- dimethylaminopyridine (49 mg, 0.40 mmol) and NN-diisopropylethylamine (1.76 ml, 10.11 mmol). The reaction mixture was stirred over weekend at room temperature. It was poured into ice water. The formed precipitate was dried and purified by flash column chromatography (DCM/MeOH 95:5 to 0:100). The crude product was suspended in Et20, filtered and dried. The product was obtained as a white solid (1.07 g, 2.49 mmol, 62 % yield). 1H NMR (400 MHz, DMSO-<) delta ppm 3.16-3.30 (m, 2 H), 4.57 (t, J=8.75 Hz, 2 H), 7.40 (dd, J=8.46 Hz, J=1.44 Hz, 1 H), 7.62 (d, J=8.34 Hz, 1 H), 7.77 (bs, 1 H), 7.85 (dd, J-8.33 Hz, J=1.91 Hz, 1 H), 8.04 (bs, 1 H), 8.50 (s, 1 H), 1 1.81 (bs, 1 H), 12.51 (bs, 1 H). LC/MS
The chemical industry reduces the impact on the environment during synthesis 2-Amino-5-(trifluoromethyl)benzoimidazole. I believe this compound will play a more active role in future production and life.
