Reaction Conditions

Reaction Steps

A solution 4-amino-2-chloro-N-(1H-indazol-6-yl)-5-nitrobenzamide (1 mmol; see Example 154) in NMP (2 mL) was added piperidin-4-yl-carbamic acid tert-butyl ester (4 mmol). The resulting mixture was heated at 100° C. for 10 h. The reaction mixture was cooled to room temperature, and diluted with water (20 mL). The solid formed was collected by filtration, washed with water, and dried in vacuo. The crude product was purified on a silica gel column chromatography using EtOAc/hexane as eluent to provide {1-[5-Amino-2-(1H-indazol-6-ylcarbamoyl)-4-nitro-phenyl]-piperidin-4-yl}-carbamic acid tert-butyl ester as a light yellow solid.
