Reaction Steps

To a round bottom flask containing [1,1-Dimethyl-2-(4-{2-[2-(2,2,2-trifluoro-ethyl)-2H-[1,2,4]triazol-3-yl]-4,5-dihydro-6-oxa-3-thia-1-aza-benzo[e]azulen-8-yl}-pyrazol-1-yl)-ethyl]-carbamic acid tert-butyl ester (0.175 g, 0.000297 mol) in methylene chloride (1.1 mL, 0.017 mol) was added trifluoroacetic acid (1.3 mL, 0.017 mol). The solution was stirred at room temperature until CO2 evolution stopped (30 minutes). The solvent was removed in vacuo and purified by reverse-phase HPLC to give 393 (21.8 mg) as a white solid. MS(ESI+) 490.1. 1H NMR (400 MHz, DMSO) δ 8.37 (d, J=9.7, 1H), 8.29 (s, 1H), 8.26 (d, J=8.3, 1H), 7.98 (s, 1H), 7.49 (dd, J=8.3, 1.7, 1H), 7.37 (d, J=1.7, 1H), 5.86 (q, J=8.7, 2H), 4.39 (t, J=5.0, 2H), 3.47 (t, J=5.0, 2H), 2.86 (s, 2H), 1.50 (s, 6H).
