Versuchsvorschrift

To a suspension of 20.0 g of 4-nitro-1,3-indanedione in 100 mL tetrahydrofuran and 20 mL of ethanol, 1.0 g of 10% Pd/C catalyst was added and the mixture hydrogenated at 50 psi until three molar equivalents of hydrogen were taken up. The catalyst was filtered off and solvent was removed from the filtrate under reduced pressure. Recrystallization from ethanol afforded 14.8 g of the title compound, m.p. 126°-128°.
