A common compound: 13726-14-2, name is 4-Chloro-3-methoxyaniline, belongs to chlorides-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below. 13726-14-2
Into a vessel containing 3 mL of dioxane was added 60 mg of Exp-5-g24 prepared in Step 2 (0.19 mmol), 31 mg of 4-chloro-3-methoxy-phenylamine (0.2 mmol), 18 mg of Pd2dba3 (0.02 mmol), 23 mg of Xantphos (0.04 mmol) and 130 mg Cs2C03 (0.4 mmol). The reaction mixture thus provided was maintained under an 2 atmosphere, refluxed for 3 hours, then cooled to ambient temperature, filtered and concentrated under reduced pressure. The residue thus provided was purified by Prep-TLC (PE:EtOAc = 1 :2) yielding 65 mg of Exp-5-g25 (calculated yield 70 %).
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, 13726-14-2, other downstream synthetic routes, hurry up and to see.
