Synthesis of N-desmethyl derivatives of 17α-acetoxy-11β(4-N,N- dimethylaminophenyl)-19-norpregna-4,9-diene-3,20-dione and mifepristone: 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 a
