Reaction Steps

In a 10 mL round-bottomed flask, 1-(3-(6-tert-butyl-8-fluoro-1-oxophthalazin-2(1H)-yl)-2-(hydroxymethyl)phenyl)-1H-pyrazole-3-carbonitrile (16 mg, 38.3 μmol, Eq: 1.00) and [hydrogen bis(dimethylphosphinito-kP)]platinum (II) (1 mg, 2.33 μmol, Eq: 0.0608) were combined with ethanol (821 μl) and water (410 μl) to give a colorless solution. The reaction mixture was heated to 80° C. and stirred for 2 h. The reaction mixture was diluted with DCM. The reaction mixture was filtered through glass fiber paper. The crude material was purified by preparative HPLC to give 1-[3-(6-tert-butyl-8-fluoro-1-oxo-1H-phthalazin-2-yl)-2-hydroxymethyl-phenyl]-1H-pyrazole-3-carboxylic acid amide (11 mg, 66%, [M+H]+ 436) of lyophilized white solid.
