Reaction Steps

To a solution of (E)-2-(3-methoxyprop-1-enyl)benzo[f][1,7]naphthyridin-5-amine (Example 34) in ethyl acetate/methanol (1:4, 0.05 M) was added 10% wt palladium on carbon (0.2 eq.). Hydrogen gas was introduced via a balloon, and the reaction was stirred for 3 hours. The mixture was filtered through a pad of celite, washing with dichloromethane. The filtrate was concentrated en vacuo and the crude product was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 0-80% ethyl acetate in hexane to give 2-(3-methoxypropyl)benzo[f][1,7]naphthyridin-5-amine as a white solid. 1H NMR (CDCl3): δ 8.64 (d, 1H), 8.46 (d, 1H), 8.19 (d, 1H), 7.66 (d, 1H), 7.53 (m, 1H), 7.31 (m, 1H), 6.56 (bs, 2H), 3.37 (t, 2H), 3.31 (s, 3H), 2.91 (t, 2H), 1.93-2.00 (m, 2H). LRMS [M+H]=268.1.
