Intermediate 9 (1 mmol) was coupled with (3-Amino-propyl)-carbamic acid tert-butyl ester (3 mmol) using EDC (2 mmol) in DMF (10 mL). The DMF was removed by rotary evaporation and the residue purified by flash chromatography on silica gel (ethyl acetate as eluent.) The resulting product was deprotected following procedure G. LC-MS showed the product had the expected M+H+ of 392. 1H NMR (Varian 300 MHz, CD3OD, shifts relative to the solvent peak at 3.3 ppm) δ 8.68 (s, 1H) 8.35-8.5 (m, 3H) 8.1 (d, 1H) 7.7 (m, 1H) 7.48 (d, 1H) 7.2 (d, 2H) 6.68 (d, 2H) 3.8 (m, 2H) 3.55 (m, 2H) 3.05 (m, 2H) 2.9 (m, 4H) 2.0 (t, 2H).
