Reaction Steps

5,5-Dimethyl-3-(2-nitrobenzyl)-[1,3]-oxazinan-2-thione (1.06 g, 3.79 mmol), iron powder (1.06 g, 19.0 mmol), ammonium chloride (0.10 g, 1.87 mmol) were suspended in ethanol (20 ml) and water (10 ml) and heated to reflux for one hour. After cooling to room temperature, the reaction mixture was filtered with suction and extracted with ethyl acetate. The organic layer was washed with a saturated brine and then dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure to obtain 3-(2-aminobenzyl)-5,5-dimethyl-[1,3]-oxazinan-2-thione (0.60 g).
