実験手順

A mixture of 2-[3-(1-triisopropylsilanyl-1H-indol-5-yl)-propyl]-[1,8]naphthyridine (125 mg, 0.282 mmol), phenyl-propynoic acid ethyl ester (98.0 mg, 0.563 mmol), and tetrabutylammonium fluoride [1.0 M] 0.85 mL, 0.85 mmol) in THF (3 mL) was stirred for 24 h. After removal of the solvent, the crude reaction mixture was purified via column chromatography on silica gel with ethyl acetate/hexane (2:1) to give the title product as an E/Z isomeric mixture in 64% yield. Mass Spectrum (LCMS, ESI) calculated for C30H28N3O2 462.2 (M+H); found 462.3.
