Procedure

A solution of 1-[(tert-butyl)oxycarbonyl]piperidine-4-carboxylic acid (0.317 g, 1.38 mmol) in 12 mL of dichloromethane was added 1-(3-dimethylaminopropyl)-3-ethyl carbodiimide hydrochloride (EDCI) (0.287 g, 1.5 mmol). The solution was stirred at room temperature for 10 min before 3-(3-aminophenyl)-1-perhydro-2H-pyran-2-yl-1H-indazole -5-carbonitrile (0.400 g, 1.25 mmol) was added as a solid. (A small volume of dichloromethane was used to rinse the flask containing the core). The reaction was stirred at room temperature for 12 hours. Even after addition of 0.5 equivalent of carboxylic acid and EDCI, the reaction could not be driven to completion. The crude mixture was partitioned between water and dichloromethane. The crude was isolated as a brown oil. The yield was not calculated.
