Intermediate 77 was coupled with tyramine following procedure Q. The resulting product was deprotected following procedure R. LC-MS showed the product had the expected M+H+ of 500. 1H NMR (Varian 300 MHz, CD3OD, shifts relative to the solvent peak at 3.3 ppm) δ 8.23 (d, 1H), 8.16 (s, 1H), 7.96 (d, 1H), 7.48 (m, 2H), 7.05 (d, 2H), 6.69 (d, 2H), 4.54 (s, 2H), 3.90 (m, 1H), 3.56 (t, 2H), 3.34 (m, 2H), 3.00 (s, 3H), 2.91 (m, 2H), 2.80 (t, 2H), 1.84 (m, 4H).
