실험 절차

To a solution of 1′-(diphenylmethyl)spiro[furo[2,3-f][1,3]benzodioxole-7,3′-indol]-2′(1′H)-one (2.10 g, 4.70 mmol) in EtOAc (100 mL) and acetic acid (0.10 mL) was added palladium on carbon (1.00 g). The reaction mixture was hydrogenated under 60 psi of hydrogen at ambient temperature for 5 days and filtered. The filtrate was concentrated in vacuo to dryness. The residue was subjected to column chromatography to yield the title compound (0.87 g, 66%) as a white powder: mp 252° C. (dec.); 1H NMR (300 MHz, CDCl3) δ 10.55 (s, 1H), 7.25-6.84 (m, 4H), 6.64 (s, 1H), 6.22 (s, 1H), 5.88 (s, 2H), 4.76-4.57 (dd, 2H); MS (ES+) m/z 282.2 (M+1).
