Versuchsvorschrift
To a stirred solution of hydroxylamine hydrochloride (437 mg, 6.3 mmol) in CH3CN at 0° C. was added Et3N and 3-tert-butyl-2-hydroxybenzaldehyde (1.02 g, 5.7 mmol). The reaction mixture was warmed up to room temperature and stirred for 24 h. The solvent was removed and the residue was dissolved in EtOAc and H2O. The layers were separated and the aqueous layer was extracted with EtOAc (2×20 mL). The combined organic layer was washed with brine, dried with Na2SO4 and concentrated under reduced pressure to provide 3-tert-butyl-2-hydroxybenzaldehyde oxime (1.01 g, 92%) as a pale yellow solid.
