반응 단계

In an autoclave, 63 g (0.275 mol) of 4-(4-morpholin-3-onyl)nitrobenzene are dissolved in 200 ml of tetrahydrofuran, admixed with 3.1 g of Pd/C (5% ig) and hydrogenated at 70° C. and a hydrogen pressure of 50 bar for 8 h. The catalyst is filtered off, the solvent is then distilled off under reduced pressure and the product is purified by crystallization from ethyl acetate. 20 g of product are obtained as a colourless to bluish solid, in a yield of 37.6% of theory.
