実験手順
4-(2-(2-methoxy-5-nitrophenoxy)ethyl)morpholine (350 mg, 1.2 mmol, 1 eq.) and tin (II) chloride dihydrate (1.4 g, 6.20 mmol, 5 eq.) were placed in EtOH (12.3 mL). The reaction mixture was heated at 60° C. and stirred for 19 hours. The reaction mixture was then concentrated under reduced pressure and the resulting residue was diluted with ethyl acetate. The organic phase was washed with a 1N NaOH aqueous solution, dried over MgSO4, filtered and concentrated under reduced pressure. The resulting residue was purified by column chromatography on silica gel to afford 4-methoxy-3-(2-morpholinoethoxy)aniline (143 mg, 46%).
