Electric Literature of 79669-50-4, 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. 79669-50-4, name is methyl 5-bromo-2-methyl-benzoate, This compound has unique chemical properties. The synthetic route is as follows.
Step 2 Compound 1251 B (1.219g, 5.32 mmol) was dissolved in CCI4 (30 mL). NBS (947 mg, 5.32 mmol) and benzoyl peroxide (66 mg, 0.27 mmol) was added. The solution was stirred at 850C for 2 hours. After cooling down, the solid was filtered and the organic layer was washed with water (10 mL). The organic layer was dried over Na2SO4, concentrated by rotary evaporator, dried under vacuum. The residue was then dissolved in NH3-MeOH (7N, 10 mL) and transferred into a 75 mL pressure bottle. The solution was stirred at 90 0C for over night. The product was purified by C18 chromatography (CH3CN/water: 5% to 90%, with addition of 0.1% HCO2H) to give compound 1251C (800mg, 71%).
The chemical industry reduces the impact on the environment during synthesis methyl 5-bromo-2-methyl-benzoate. I believe this compound will play a more active role in future production and life.
