Reaction Steps

4-Allyl-1H-indol-5-ol (Example 54)120 mg, 0.69 mmol) was dissolved in EtOH (10 mL), and 20% palladium (II) hydroxide on carbon (20 mg) and ammonium formate (349.5 mg, 5.45 mmol) were added. After stirring for 30 min at rt, the mixture was heated to 40° C. for 2 h. After cooling to rt, the catalyst was removed by filtration, and the filtrate concentrated under reduced pressure. The residue was taken up in water, and the aqueous phase was extracted with EtOAc (2×). The combined organic phases were dried over Na2SO4, filtered, and concentrated under reduced pressure to give 91 mg (75%) of the title compound as a white solid. 1H NMR (400 MHz, CDCl3): δ 1.04 (t, 3H), 2.74 (m, 2H), 2.88 (t, 2H), 6.49 (s, 1H), 6.75 (d, 1H), 7.10 (d, 1H), 7.18 (s, 1H), 8.00 (br, 1H).
