実験手順
This intermediate was prepared according to the procedure escribed for the synthesis of Compound 114 by replacing 3,4-difluorophenylhydrazine with 2-fluoro-5-chlorophenylhydrazine in step 1, and replacing tert-leucine methyl amide with tert-leucine tert-butyl ester in step 3. LC-MS (+ESI) m/z=466.3 [M+H]+.
