Application of 937046-98-5, 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. 937046-98-5, name is 7-Bromopyrrolo[2,1-f][1,2,4]triazin-4-amine, This compound has unique chemical properties. The synthetic route is as follows.
To a suspension of N-methyltetrahydro-2H-pyran-4-amine (541 mg, 4.69 mmol) and (3-(bromomethyl)phenyl)boronic acid (756 mg, 3.52 mmol) in acetonitrile (8 mL) was added K2C03 (973 mg, 7.04 mmol) under anhydrous conditions. After stirring at room temperature for 10 h, the reaction mixture was concentrated, phosphoric acid,potassium salt (1.50 g, 2.35 mmol), 7-bromopyrrolo[2,1-f][1,2,4]triazin-4-amine (500 mg, 2.347 mmol), dioxane (8 mL) and water (4 mL) were added. The reaction vessel was evacuated, backfilled with N2 and then degassed by bubbling N2 with sonication. Tetrakis triphenylphosphine (271 mg, 0.235 mol) was added and the degassing process was repeated. The resulting reaction mixture was heated at 140 C in a microwave for 45mm. The reaction complex was cooled, filtered, and washed with water. The filtrate was extracted with ethyl acetate (10 mL x 3). The organic layers were combined, dried and concentrated. The crude mixture was dissolved in DMF, and purified by preparative LC Method C to obtain 7-(3 -((methyl(tetrahydro-2H-pyran-4-yl)amino)methyl)phenyl) pyrrolo[2,1-f][1,2,4]triazin-4-amine, TFA (636 mg, 60% yield). LC/MS (M+H) =338.30.
The chemical industry reduces the impact on the environment during synthesis 7-Bromopyrrolo[2,1-f][1,2,4]triazin-4-amine. I believe this compound will play a more active role in future production and life.
