Reaction Steps

Sodium hydride (60% dispersion in oil, 2.45 g) was added to ethanol (100 ml), to which was added 3-carboethoxy-2-piperidone (10.0 g). The reaction mixture was stirred for 15 minutes, to which was added 2-nitrobenzyl bromide (13.2 g) at room temperature. The reaction mixture was stirred at 60° C. for 3 hours. Water was added to the reaction mixture, which was concentrated. The residue was diluted with water and extracted with ethyl acetate. The organic layer was washed with water and a saturated aqueous sodium chloride solution, then dried and concentrated. The obtained crude crystals were recrystallized from ethyl acetate-hexane to give the entitled compound (14.6 g).
