Reaction Steps

In a 25 mL container, 1-(3-(6-tert-butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)-2-formylphenyl)-1H-pyrazole-3-carbonitrile (18 mg, 43.3 μmol, Eq: 1.00), sodium borohydride (6.56 mg, 173 μmol, Eq: 4) were combined with CH2Cl2 (2 mL) and MeOH (1 mL) to give a white suspension. The mixture was stirred for 1 hr. The reaction mixture was poured into 25 mL sat NH4Cl and extracted with EtOAc (3×25 mL). The organic layers were dried over MgSO4 and concentrated in vacuo. The organic layer was concentrated to give 1-(3-(6-tert-butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)-2-(hydroxymethyl)phenyl)-1H-pyrazole-3-carbonitrile (16 mg, 99%) of white product.
