Participants

Reaction Steps

tert-Butyl (3R,4R)-3-amino-4-phenylpiperidine-1-carboxylate (124 mg) was dissolved in methylene chloride (2 ml), and thereto were added triethylamine (125 μl) and 2-nitrobenzene sulfonyl chloride (109 mg) at 0° C., and the mixture was stirred at room temperature for 3 hours. To the reaction solution was added a saturated aqueous ammonium chloride solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous sodium chloride solution, dried over sodium sulfate, filtered, and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (the developing solvent: hexane/ethyl acetate=1/1) to give the title compound (202 mg).
