Product Description

On the preparation of this Intermediate of Fulvestrant cas number 875573-66-3, most manufacturers use nandrolone as the starting material, there are a small number of manufacturers using estradiol as raw materials. The preparation process first reacted with estradiol and 3,4-dihydropyran catalyzed by p-toluenesulfonic acid. The product was then reacted with trimethyl borate / H2O2 to produce alcohol hydroxyl groups at the 6-position of steroids,And then oxidized with pyridinium chlorochromate to form ketone carbonyl compounds, and the ketone carbonyl compound use potassium tert-butoxide as soda, take the nucleophilic substitution reaction of C2F5 (CH2) 3S (CH2) 9Br and then the product was further treated with BF3Et2O / Et3SiH to remove 6-position Carbonyl, the pyran protecting group was removed by hydrolysis using K2CO3 to give the target compound Fulvestrant intermediate 875573-66-3. The biggest drawback of this preparation method is that waste water contains a lot of heavy metals which is difficult to handle, wastewater discharge is difficult to meet environmental requirements.
