8.1 g (32 mMol) of 4-[2-(4-Nitro-phenoxy)-ethyl]-morpholine is dissolved in 100 mL of ethanol and subjected to catalytic hydration at rt using 681 mg of Pd/C. After filtration trough HYFLO and removal of the solvent under reduced pressure, the crude product is purified by bulb-to-bulb distillation (0.13 mbar: 200° C.) to obtain 4-(2-morpholin-4-yl-ethoxy)-phenylamine. Title compound: ES-MS: 223 [M+H]+; single peak at tR=3 min (System 2).
