実験手順
To a solution of 7-nitro-3,4-dihydro-2H-naphthalen-1-one (500 mg, 2.62 mmol) in pyridine (2 mL) was added hydroxylamine solution (1 mL, 50% solution in water). The reaction was stirred at room temperature for 1 h, then concentrated and purified by column chromatography (10-50% ethyl acetate-hexanes) to yield 7-nitro-3,4-dihydro-2H-naphthalen-1-one oxime (471 mg, 88%). HPLC ret. time 2.67 min, 10-99% CH3CN, 5 min run; ESI-MS 207.1 m/z (MH+).
