Procedure
6H-1-Thia-5,6-diaza-as-indacene-2-carboxylic acid (30 mg, 0.138 mmol) is mixed with DIEA (0.030 ml, 0.172 mmol) and HATU (57.71 mg, 0.151 mmol) in 2 ml DMF at room temperature. 3-Amino-N-(3-trifluoromethyl-phenyl)-benzamide (38.6 mg, 0.138 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 12.09 (s, 1H), 10.70, (s, 1H), 10.55 (s, 1H), 8.84 (s, 1H), 8.29 (s, 1H), 8.19 (s, 1H), 8.03-7.97 9 (m, 2H), 7.69 (d, 1H, J=7.6 Hz), 7.57-7.49 (m, 3H), 7.40 (d, 1H, J=7.6 Hz), 6.72 (dd, 1H, J=3.2, 1.6 Hz; MS m/z 481.1 (M+1).
