Synthesis of N-desmethyl derivatives of 17alpha-acetoxy-11beta-(4-N,N-dimethylaminophenyl)-19-norpregna-4,9-die ne-3,20-dione and mifepristone1: substrates for the synthesis of radioligands.
The syntheses of N-desmethyl derivatives of CDB-2914 and the mono-N-desmethyl derivative of Mifepristone are described. We also describe the use of the mono-desmethyl derivatives as substrates for the synthesis of N-tritomethyl derivatives of CDB-2914 and Mifepristone with high specific activity (ca. 80 Ci/mmol), which serve as radioligands for radioimmunoassay.
