Reaction Steps

A mixture of N-(1-nitro-5,6,7,8-tetrahydronaphthalen-2-yl)acetamide (800 mg, 3.88 mmol) in a 10 M solution of hydrochloric acid in MeOH were heated to reflux for 4 h. After concentration, the residue was basified with 2 N aqueous solution of NaOH to pH 9, then extracted with EtOAc (50 mL×2). The organic layer was washed with brine (30 mL), dried, and concentrated. The residue was dissolved in DMF (20 mL), cooled to 0° C., and NaH (60% dispersion in mineral oil, 0.155 mg, 3.88 mml) was added in one portion. Iodomethane (582 mg, 3.88 mmol) was added dropwise. The resulting mixture was stirred at the same temperature for another 2 h. The reaction mixture was quenched by ice (20 g) and then extracted with EtOAc (50 mL×2). The organic layer was washed with brine (20 mL), dried, and concentrated to give a yellow solid (190 mg). ESI MS: m/z 207 [M+H]+.
