Procedure

Diethyl 3-(4-(2-(5-amino-8-methylbenzo[f][1,7]naphthyridin-2-yl)ethyl)-3-methylphenoxy)propylphosphonate was prepared following an analogous procedure to the preparation described for Example 139, but using 4-(2-(5-amino-8-methylbenzo[f][1,7]naphthyridin-2-yl)ethyl)-3-methylphenol (from Example 50) with diethyl 3-bromopropylphosphonate. 1H NMR (Acetone-d6): δ 9.52 (s, 1H), 9.47 (s, 1H), 9.03 (d, 1H), 8.21 (s, 1H), 7.93 (d, 1H), 7.84 (d, 1H), 7.60 (br, 2H), 7.53 (s, 1), 7.45 (d, 1H), 4.76-4.91 (m, 6H), 3.93 (t, 2H), 3.81 (t, 2H), 3.24 (s, 3H), 3.06 (s, 3H), 2.76-2.86 (m, 2H), 2.61-2.72 (m, 2H), 2.07 (t, 6H).
