Reaction Steps

1-Methyl-1,6-dihydro-1,5,6-triaza-as-indacene-2-carboxylic acid (35 mg, 0.162 mmol) is mixed with DIEA (0.030 ml, 0.172 mmol) and HATU (67.8 mg, 0.178 mmol) in 2 ml DMF at room temperature. N-(3-Amino-phenyl)-3-trifluoromethylbenzamide (45.53 mg, 0.162 mmol) is added into the reaction mixture 0.5 hours later. After stirring at room temperature for 2 hours, the reaction mixture is concentrated and purified by Prep-HPLC to afford the title compound as a TFA salt: 1H NMR 400 MHz (DMSO-d6) δ 12.37 (s, 1H), 10.56, (s, 2H), 8.87 (s, 1H), 8.40 (s, 1H), 8.33 (s, 1H), 8.29 (d, 1H, J=8.0 Hz), 7.98 (d, 1H, J=7.6 Hz), 7.84 (t, 1H, J=8.0 Hz), 7.68 (s, 1H), 7.57-7.54 (m, 3H), 7.37 (t, 1H, J=8.0 Hz), 7.09-7.07 (m, 1H), 4.32 (s, 3H) Hz; MS m/z 481.1 (M+1).
