Related Products of 56133-86-9, 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. 56133-86-9, name is 2-(2,5-Dichlorophenyl)ethanamine, This compound has unique chemical properties. The synthetic route is as follows.
General procedure: Under nitrogen atmosphere, ethanol (30 mL), immediate III (3 mmol) and titanium (IV) isopropoxide (9 mmol) were added to a three-necked round bottom flask and stirred for 0.5 h, then the substituted ethylamine (3 mmol) was dropped into the solution and stirred for 3 h at room temperature. Subsequently, sodium borohydride (4.5 mmol) was added to the flask slowly, the reductive amination reaction was maintained for 3 h. According to the TLC monitoring results, the ammonia water (2 mol L-1, 10 mL) was poured into the flask to quench the reaction. The resulting mixture was filtered in vacuum and evaporated on rota vapor (Buchi). Hereafter, dissolved the residue with ethyl acetate (50 mL), and the solution was washed with 2 mol L-1 hydrochloric acid (30 mL), saturated aq NaHCO3 solution (30 mL), and brine (40 mL), successively, dried over anhydrous Na2SO4 and filtered. Solvent was evaporated in vacuum, and the residue was purified by silica gel column chromatography (petroleum ether / ethyl acetate as eluents). Finally, the samples were recrystallized from ethyl acetate / petroleum ether to afford target compounds with higher purity.
The chemical industry reduces the impact on the environment during synthesis 2-(2,5-Dichlorophenyl)ethanamine. I believe this compound will play a more active role in future production and life.
