Reaction Steps

A mixture of 8-(prop-1-en-2-yl)benzo[f][1,7]naphthyridin-5-amine (from the previous step) (1.0 eq) and Pd/C (wet, 10% wt) in EtOH was stirred under H2 balloon overnight. The reaction mixture was diluted with DCM. The Pd/C was filtered off through celite, and the filtrate was concentrated en vacuo to obtain a crude residue. The crude material was purified by flash chromatography on a COMBIFLASH® system (ISCO) using 0-60% EtOAc/Hexanes to give 8-isopropylbenzo[f][1,7]naphthyridin-5-amine as a yellow solid: 1H NMR (acetone-d6): δ 8.98 (dd, 1H), 8.88 (dd, 1H), 8.37 (d, 1H), 7.83 (dd, 1H), 7.49 (d, 1H), 7.27 (dd, 1H), 6.66 (br s, 2H), 3.10-3.00 (m, 1H), 1.33 (d, 6H). LRMS [M+H]=238.1.
