Participants

Reaction Steps

A mixture of 5-(2-chlorophenyl)-3-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-4-oxo-4,5-dihydro-1H-pyrazolo[4,3-c]pyridine-6-carbaldehyde obtained in Step J (260 mg), 2,2,2-trifluoro-N-(2,2,2-trifluoroacetoxyl)acetamide (140 mg), pyridine (0.100 mL) and benzene (3.10 mL) was refluxed for 1 hr, and cooled to room temperature. To the reaction mixture was added water, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (203 mg).
