Reaction Steps

Intermediate 130 was coupled with tyramine following procedure F. The product was deprotected following procedure G2. LC-MS showed the product had the expected M+H+ of 418. 1H NMR (Varian 300 MHz, CD3OD, shifts relative to the solvent peak at 3.3 ppm) δ 8.35 (s, 1H) 8.29 (d, 2H) 8. 7.81 (d, 1H) 7.68 (t, 1H) 7.49 (d, 1H) 7.2-7.2 (m, 3H) 6.68 (d, 2H) 4.8 (d, 1H) 4.17 (d, 1H) 3.85 (br s, 2H) 3.68 (d, 1H) 3.1-3.6 (m, 6H) 2.9 (t, 2H) 2.2 (m, 1H) 1.9 (m, 1H) 1.1 (t, 3H).
