実験手順
8-Phenethylbenzo[f][1,7]naphthyridin-5-amine was prepared from 5-aminobenzo[f][1,7]naphthyridine-8-carbaldehyde (from Example 87) with benzyltriphenylphosphonium bromide following the procedures described for Example 91 (wittig reaction) and Example 92 (reduction). 1H NMR (acetone-d6): δ 8.99 (dd, 1H), 8.88 (dd, 1H), 8.35 (d, 1H), 7.83 (dd, 1H), 7.49 (d, 1H), 7.29-7.15 (dd, 6H), 6.70 (br s, 2H), 3.10-3.00 (m, 4H). LRMS [M+H]=300.1.
