Indazole-3-carboxylic acid (30 mg; 0.182 mmol), DCC (56 mg, 0.273 mmol) and DMAP (2 mg) were dissolved in DCM:DMF (1:1, 4 ml). 2-(5-(3,4-dichlorophenyl)furan-2-yl)ethanamine (46 mg, 0.182 mmol) was added and the reaction mixture was stirred for overnight at RT. DCM (30 ml) was added and organic layer washed with water (3×15 ml). Combined organic phases were dried over Na2SO4, evaporated and purified by chromatography (silica column, eluent: 1% MeOH/DCM) to give 25 mg (34%) of the title compound. 1H-NMR (400 MHz; d6-DMSO): δ 3.00 (t, 2H), 3.63 (q, 2H), 6.37 (d, 1H), 7.02 (d, 1H), 7.23 (t, 1H), 7.41 (t, 1H), 7.60 (d, 1H), 7.61 (d, 2H), 7.85 (d, 1H), 8.16 (d, 1H), 8.54 (d, 1H), 13.56 (s, 1H).
