Procedure
144 mg (0.75 mmol) of N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (DAPECI) are added to a solution of 146 mg (0.60 mmol) of 5-(3-amino-1H-indazol-5-yl)furan-2-carboxylic acid and 73.9 mg (0.60 mmol) of 3-hydroxybenzylamine in 1 ml of DMF, and the mixture is stirred at room temperature for 4 hours. Water is added to the reaction mixture, which is extracted with ethyl acetate. The organic phase is dried over sodium sulfate and evaporated, and the residue is purified by preparative HPLC, giving N-3-hydroxybenzyl-5-(3-amino-1H-indazol-5-yl)furan-2-carboxamide (“62”) as yellowish solid, ESI 349.
