- Molecular Weight:215.04
Yield:619-42-1 99%
Reaction Conditions:
with 1,3-dichloro-5,5-dimethylhydantoin at 60; for 7 h;
Steps:
3 Example 3: Preparation of methyl 4-bromobenzoate
Add 10 mmol 4-bromobenzoic acid, 100 mmol methanol, and 1.5 mmol dichlorohydantoin into a 50 mL three-necked flask, set up a reflux device, and stir and react at 60°C for 7 hours.After the methanol was recovered by rotary evaporation, it was transferred to a separatory funnel, and 20 mL of ethyl acetate was added, washed with 5% sodium carbonate solution, washed with water, dried with anhydrous sodium sulfate, and the solvent was removed under reduced pressure to obtain methyl 4-bromobenzoate. Yield 99%,
