Related Products of 174403-69-1, 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. 174403-69-1, name is Methyl 4-fluoro-2-methylbenzoate, This compound has unique chemical properties. The synthetic route is as follows.
A mixture of pyrazole (100 mg, 1.47 mmol), methyl 4-fluoro-2-methylbenzoate (123.51 mg, 0.73 mmol) and potassium carbonate (609.0 mg, 4.41 mmol) in N,N-dimethylformamide (5 mL) was stirred at 60 C for 16 h. The reaction was poured into water (5 mL) and extracted with EtOAc (20 mL). The organic extract was washed with water (20 mL x 2) and brine (10 mL), dried over Mg504 and concentrated. The residue was purified by prep-TLC (33% ethyl acetate in petroleum ether, Rf = 0.3) to afford methyl 2-methyl-4-(1H-pyrazol-1-yl)benzoate (50 mg, 15.7% yield) as a white solid. LCMS (Method 5-95AB): tR =0.732 mi [M + Hj = 216.9.
The chemical industry reduces the impact on the environment during synthesis Methyl 4-fluoro-2-methylbenzoate. I believe this compound will play a more active role in future production and life.
