Participants

Reaction Steps

A solution 4-amino-2-chloro-N-(1H-indazol-6-yl)-5-nitrobenzamide (1 mmol; see Example 154) was reacted with piperazine following the procedure described in Example 163 to afford 4-amino-N-(1H-indazol-6-yl)-5-nitro-2-piperazin-1-ylbenzamide. The product thus obtained was treated with BOC anhydride as in Example 163 to obtain 4-[5-amino-2-(1H-indazol-6-ylcarbamoyl)-4-nitro-phenyl]-piperazine-1-carboxylic acid tert-butyl ester.
