2,4-DIBROMOANISOLE CAS 21702-84-1 can be widely used in laboratory research and development and pharmaceutical research and development.
Shandong Believe Chemical Pte. Ltd. 2,4-DIBROMOANISOLE CAS 21702-84-1 is a very important intermediate in organic synthesis and chemical medicine, which can be widely used in laboratory research and development and pharmaceutical research and development.
Preparation method: add 2,4-dibromofluorobenzene (20.0g, 0.08mol, 1eq.) and anhydrous DMF (350ml) to a 500ml round bottom flask, slowly add sodium methoxide (5.2g, 0.09mol, 1.2eq.) to the round bottom flask, stir vigorously at room temperature overnight, and then add 5% chemicalbookhcl to stop the reaction.
CH2Cl2 extraction (50ml × 3) Wash the organic phase with distilled water (50ml × 3) Dry the organic phase with anhydrous magnesium sulfate, filter to remove magnesium sulfate, spin to remove the solvent to obtain a pale yellow solid, and purify it with silica gel chromatography column (eluent: petroleum ether) to obtain 30g of white solid, with a yield of 95%.
