Synthesis
General procedure for the synthesis of 4-morpholinomethylaniline from 4-(4-nitrobenzyl)morpholine: 4-(4-nitrobenzyl)morpholine (2.22 g, 10 mmol) was dissolved in methanol under nitrogen atmosphere and 200 mg of Pd/C catalyst was added. Hydrogen was then passed through to carry out the hydrogenation reaction, which lasted for 6 hours. Upon completion of the reaction, the catalyst was removed by filtration and the filtrate was collected. The filtrate was concentrated to give 1.83 g of 4-morpholinomethylaniline solid in 95% yield.
