Related Products of 38762-41-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 38762-41-3, name is 4-Bromo-2-chloroaniline belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
A degassed solution of 3-trifluoromethanesulfonyloxy-furo[3,2-c]pyridine-2- carboxylic acid ethyl ester (300 mg, 0.88 mmol), 4-bromo-2-fluoro aniline (201 mg, 0.97 mmol), Pd2dba3 (40 mg, 0.044 mmol), Xantphos (59 mg, 0.044 mmol) and potassium phosphate tribasic (373 mg, 1.76 mmol) in toluene (5 ml) was heated at reflux under an argon atmosphere for 16 hours. The reaction mixture was filtered and concentrated in vacuo. The resultant residue was purified by flash chromatography (Si-SPE, pentane: diethyl ether, gradient 80:20 to 50:50) to afford the title compound as a yellow solid (177 mg, 51%). LCMS (method B): Rx = 3.76 min, M+H+ = 395 / 397.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 4-Bromo-2-chloroaniline, other downstream synthetic routes, hurry up and to see.
