9/8/2021 News Discovery of 16452-01-0

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, 3-Methoxy-4-methylaniline, other downstream synthetic routes, hurry up and to see.

Application of 16452-01-0, The chemical industry reduces the impact on the environment during synthesis 16452-01-0, name is 3-Methoxy-4-methylaniline, I believe this compound will play a more active role in future production and life.

g. 2-bromo-5-methoxy-4-methyl-aniline. To a solution of 3-methoxy-4-methyl-aniline (8.19 g, 59.71 mmol) in dichloromethane (200 mL), was added tetrabutylammonium tribromide (28.79 g, 59.71 mmol) and the reaction mixture was stirred at room temperature for 2.5 hrs. Aqueous NaHCO3 was added and the layers separated. The aqueous layer was further extracted with dichloromethane and the combined organics washed successively with water and brine, dried over MgSO4, filtered and evaporated. The residue was chromatographed on silica gel (20% ethyl acetate in hexane) to give 11.05 g of 2-bromo-5-methoxy-4-methyl-aniline (85% yield). 1H NMR (300 MHz; CDCl3): 2.09 (s, 3 H), 3.75 (s, 3 H), 3.95 (br s, 1 H), 6.27 (s, 1 H), 7.13 (s, 1 H).
