Participants

Reaction Steps

A solution of 1,1-dimethylethyl 4-(5-bromo-7-cyano-1H-indazol-3-yl)-1-piperidine-carboxylate (Intermediate 3) (0.200 g, 0.493 mmols) and trifluoroacetic acid (0.25 mL) in dichloromethane (5 mL) was stirred at room temperature for 2 hrs. The solution was cooled and the solvent removed in vacuo to give the crude amine (222 mg) trifluoroacetate salt, which was used in the next step without further purification.
