Acetic Acid → HCID 89586301, compound

Participants

Reaction Steps

3-(1-Phenyl-1H-pyrazol-5-yl)-1-piperidin-4-ylpyridazin-4(1H)-one (0.20 g), acetone (0.23 mL) and acetic acid (1.0 mL) were dissolved in THF (10 mL), sodium triacetoxyborohydride (0.66 g) was added, and the mixture was stirred at room temperature overnight. The reaction mixture was concentrated under reduced pressure, and neutralized with saturated sodium hydrogen carbonate. Sodium chloride was added to saturation, and the mixture was extracted with ethyl acetate/THF. The extract was dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (NH, THF) and recrystallized from ethyl acetate/hexane to give the title compound (0.15 g).
