Reaktionsschritte

To a solution of {[1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carbonyl]-amino}-acetic acid methyl ester (0.50 g, 1.5 mmol) in EtOH (6 mL) was added hydrazine hydrate (2 mL) and the mixture was warmed at 60° C. After 18 hours, the mixture was cooled to room temperature and poured into water (100 mL). The solid was collected by filtration to afford 1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carboxylic acid hydrazinocarbonylmethyl-amide (purity 90%).
