참여 물질

반응 단계

To a solution of α-tetralone (10 g, 68.5 mmol) in anhydrous MeOH (175 mL), hydroxylamine hydrochloride (7.6 g, 109.6 mmol) and triethylamine (15.3 mL, 109.6 mmol) were added. The mixture was stirred at room temperature for 16 hrs, followed by removal of the solvent in vacuo. The residue was dissolved in DCM, washed with water and brine, dried (Na2SO4), filtered and concentrated in vacuo to yield crude 3,4-dihydro-2H-naphthalen-1-one oxime (12 g). MS [M+H]+: 162.1; tR=2.03 min. (method 1)
