Dimethyl Sulfate → 1-(Methoxymethyl)-2-nitrobenzene

関与物質

反応手順

To a solution of (2-nitrophenyl)methanol (5.13 g, 33.50 mmol) in DCM (75 mL) was added 3.35 N NaOH (75 mL, 251.2 mmol) in water at ambient temperature and stirred at ambient temperature for 10 minutes. Me2SO4 (6.38 ml, 67.0 mmol) and tetrabutylammonium hydrogen sulfate (0.57 g, 1.68 mmol) were added and the mixture stirred vigorously for 20 hours at ambient temperature. The reaction mixture was diluted with DCM (100 mL) and organic layer was separated, washed with brine, dried (sodium sulfate), filtered and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel (5:1 hexane/ethyl acetate) to give 1-(methoxymethyl)-2-nitrobenzene (5.12 g, 91.4%) as an oil.
