실험 절차

6-Hydroxy-5-methoxy-1-indanone (114 mg, 0.64 mmol) was subjected to reaction with (4-nitrobenzyl)hydroxylamine hydrochloride (149 mg, 0.73 mmol) in ethanol (5 mL) and pyridine (0.6 mL, 7.74 mmol) under the same conditions as described for (E)-6,7-dimethoxy-3,4-dihydronaphthalen-1(2H)-one O-4-nitrobenzyl oxime. The solid obtained on work up was recrystallized (isopropanol) to yield the title compound (101 mg, 48%) as off-white crystals, m.p. 146-149° C.
