実験手順
3-tert-butyl-2-hydroxybenzaldehyde oxime (550 mg, 2.9 mmol) in EtOAc (10 mL) and MeOH (10 mL) was hydrogenated at balloon pressure in the presence of 10% Pd on carbon (100 mg) for 15 h. The reaction mixture was filtered over celite and concentrated. The residue was dissolved in EtOAc and 0.5 N HCl (10 mL). The layers were separated and the aqueous layer was treated with 1N NaOH solution until pH=9. The resulting aqueous layer was extracted with CHCl3 (3×10 mL). The combined CHCl3 was washed with brine, dried with Na2SO4 and concentrated under reduced pressure to provide to desired product (123 mg, 23%).
