Vorschrift

3-[5-(3-[1,8]Naphthyridin-2-yl-propyl)-indol-1-yl]-3-phenyl-acrylic acid ethyl ester (30.0 mg, 0.484 mmol) in methanol (2 mL) was stirred under hydrogen in the presence of 10% palladium on carbon (15.0 mg) at room temperature for 3 days. Then, the reaction mixture was filtered through celite and purified via column chromatography on silica gel (methylene chloride/methanol) (95/5) to give the title product as yellow oil (20.0 mg, 66% yield). 1H NMR (CDCl3) δ 8.2 (d, 1H), 8.0 (m, 1H), 7.45 (m, 2H), 7.27 (m, 2H), 6.9-7.2 (m, 4H), 6.5 (1H), 6.3 (1H), 6.20 (m, 1H), 6.10 (m, 1H), 4.15 (m, 2H), 3.4 (m, 2H), 3.3 (m, 4H), 2.6 (m, 4H), 2.1 (m, 2H), 1.89 (m, 2H). Mass Spectrum (LCMS, ESI) calculated for C30H34N3O2 468.27 (M+H); found 468.3.
