Intermediate 137 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 434. 1H NMR (Varian 300 MHz, CD3OD, shifts relative to the solvent peak at 3.3 ppm) δ 8.47 (s, 1H) 8.36 (d, 2H) 7.88 (d, 1H) 7.74 (t, 1H) 7.61 (d, 1H) 7.15 (d, 2H) 6.68 (d, 2H) 4.68 (dd, 1H) 4.39 (s, 2H) 3.96 (t, 2H) 3.84 (dd, 2H) 3.52 (t, 2H) 3.44 (t, 2H) 2.95 (t, 2H).
