| titleOfInvention | Process for the preparation of estrone and/or estradiol-derivates |
| abstract | Process for the preparation of a compound of general formula (II) wherein R1 and R2 independently are hydrogen or a hydroxy- or hydrocarbyl group; or wherein R1 and R2 together are a double bonded oxygen; R3 is hydrogen; R' 4 is a nitrobenzophenone group; and R5 and R6 independently are hydrogen or a hydroxy- or hydrocarbyl group; from a compound of general formula (I) wherein, R1, R2 R3, R5 and R6 are as defined above and R4 is hydrogen; wherein the compound of formula (I) is reacted under alkaline conditions with 2-chloro-5-nitrobenzophenone in the presence of an alkanolic solvent and the compound of formula (II) is directly crystallized from this alkanolic solvent. Complex of an alkanol and a compound of general formula (II) obtainable from the above process and processes wherein the above process or complex are used. |
