Application of 7745-91-7, These common heterocyclic compound, 7745-91-7, name is 3-Bromo-4-methylaniline, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
[00236] A suspension of 3 -bromo-4-methylaniline (184 mg, 1.0 mmol), 2-(tributylstannyl)- 1,3-oxazole (430 mg, 1.2 mmol), CuO (8 mg, 0.1 mmol) and Pd(PPli3)4 (1 15 mg, 0.1 mmol) in dioxane (2 mL) was stirred at 100 C for 3 hours under argon atmosphere on microwave synthesizer. The crude product was purified by prep-HPLC (MeCN/10 mM NH4HCO3) to give 4-methyl-3-(l,3-oxazol-2-yl)aniline (92 mg, 52%) as an oil. ES-MS m/z: 175.2 [M + H]+. LC- MS Purity (254 nm): > 99%; tR= 1.31 min.
The synthetic route of 7745-91-7 has been constantly updated, and we look forward to future research findings.
