A mixture of 21 g (0.043 mol) of N,N'-didecyl-5-nitro-1,3-benzenedicarboxamide and 7.0 g of 10% palladium on carbon in 250 ml of tetrahydrofuran was shaken under hydrogen pressure (52 psi initially) on a Parr Hydrogenator for 17 hours. The catalyst was removed by filtration and the solvent was removed from the filtrate at reduced pressure to give a solid which was recrystallized from methanol-water to give 15.3 g (77% yield, mp 188°-189°) of 5-amino-N,N'-didecyl-1,3-benzenedicarboxamide.
