Versuchsvorschrift

A solution of N-tert-butyl-N-ethoxalyl-2-nitroaniline (45 g) in absolute ethanol (500 ml) was hydrogenated at standard conditions (1 atm.) using 5% Pd/C (5 g) as catalyst. The catalyst was filtered off and the solvent was removed in vacuo. This left an oil, which crystallized upon standing, m.p. 64°-65° C.
