Versuchsvorschrift

A crudely purified product of cis-2-{[2-(2-methyl-2H-indazol-4-yl)cyclopropyl]methyl}-1H-isoindole-1,3(2H)-dione was dissolved in ethanol (6.5 mL), and hydrazine monohydrate (3 mL) was added. The mixture was heated under reflux for 20 min. The solvent was evaporated under reduced pressure. Saturated aqueous sodium hydrogen carbonate solution was added to the residue, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate and the solvent was evaporated under reduced pressure to give the title compound as a crudely purified product.
