Procedure

To a solution of 2.6 g 4-(4-Nitro-phenyl)-morpholin-3-one in 350 mL ethyl acetate and 17 mL ethanol 13.2 g SnCl2 dihydrate were added and the reaction mixture was heated to reflux for 2 h. Then after cooling to RT the mixture was stirred for 16 h. The precipitated product was collected by filtration and was pure enough for the next reaction step. Yield: 2.07 g.
