Reaction Steps

A mixture of 2-(4-cyanopyrazol-1-yl)-1-[1-(4-fluorophenyl)-6,7-dihydro-5H-pyrazolo[4,3-b]pyridin-4-yl]ethanone (0.175 g, 0.50 mmol), NH2OH—HCl (0.500 g, 7.2 mmol) and NEt3 (1.00 mL, 7.1 mmol) in EtOH (3 mL) was heated at 90° C. for 5 hrs. It was then cooled to rt. The mixture was partitioned between IPA/CHCl3 (1:2, 50 mL) and sat. NaHCO3 (30 mL). The organic layer was separated, dried over Na2SO4 and concentrated in vacuo to obtain 1-[2-[1-(4-fluorophenyl)-6,7-dihydro-5H-pyrazolo[4,3-b]pyridin-4-yl]-2-oxo-ethyl]-N′-hydroxy-pyrazole-4-carboxamidine (0.115 g, 60%).
