Intermediate 109 was coupled with tyramine following procedure F. The resulting product was deprotected following procedure G2. LC-MS showed the product had the expected M+H+ of 520. 1H NMR (Varian 300 MHz, CD3OD, shifts relative to the solvent peak at 3.3 ppm) δ 8.51 (s, 1H), 8.29 (d, 2H), 7.81 (d, 1H), 7.55 (m, 3H), 7.34 (d, 1H), 7.25 (s, 1H), 7.02 (m, 4H), 6.69 (s, 2H), 4.54 (m, 2H), 4.08 (m, 1H), 3.90 (m, 2H), 3.61 (m, 4H), 3.25 (m, 4H), 2.92 (t, 2H).
