Procedure

A solution of 5-morpholin-4-yl-2-nitro-phenylamine (4.0 g, 0.02 mol) in acetic acid (100 mL) and ethanol (100 mL) was treated with hydrogen gas (60 psi) for 30 min in the presence of palladium on carbon catalyst (0.5 g, 10% Pd). The catalyst was removed by filtration through CELITE®, and the filtrate was concentrated to a syrup and dried in vacuo to afford the intermediate 4-morpholin-4-yl-benzene-1,2-diamine as a crude green solid (3.2 g).
