A mixture of 2-(6-chloro-1-methyl-1H-indazol-3-yl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxylic acid (70 mg, 0.23 mmol), 3-aminobenzonitrile (41 mg, 0.344 mmol), EDCI (88 mg, 0.46 mmol) and DMAP (56 mg, 0.46 mmol) in DMF (5 mL) was stirred at room temperature for 16 hours. Then the mixture was poured into water (5 mL) and filtered to give a crude product. The crude product was triturated with DMSO and MeOH, then decanted and dried to give 2-(6-chloro-1-methyl-1H-indazol-3-yl)-N-(3-cyanophenyl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (20 mg, 20%) as a white solid. MS: (M+H)+=428; 1H NMR (300 MHz, DMSO): δ 10.55 (s, 1H), 8.81 (s, 1H), 8.55-8.50 (m, 2H), 8.15 (brs, 1H), 8.03-8.00 (m, 1H), 7.92 (s, 1H), 7.59 (d, 1H, J=8.1 Hz), 7.48 (d, 1H, J=7.8 Hz), 7.26 (d, 1H, J=7.5 Hz), 4.14 (s, 3H).
