Participants

Reaction Steps

1-Hydroxyimino-6-methoxy-3-phenyl-1H-indene-2-carboxylic acid ethyl ester (1.00 g, 3.09 mmol) obtained in Step 1 was dissolved in methanol (100 mL), and 10%-palladium (583 mg) was added thereto. The mixture was stirred for 15 hrs at RT while providing H2 gas thereto using a balloon, filtered through celite, and concentrated under a reduced pressure. The resulting residue was purified by flash chromatography to obtain 786 mg of the titled compound (yield: 82%).
