Procedure

To a stirred mixture of 2-(1,6-dimethyl-1H-indazol-3-yl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxylic acid (80 mg, 0.26 mmol) and 1-aminocyclopropanecarbonitrile hydrochloride (46 mg, 0.39 mmol) in DMF (3 mL) was added EDCI (100 mg, 0.52 mmol) followed by DMAP (63 mg, 0.52 mmol). The mixture was stirred at room temperature for 16 hours. Then the mixture was poured into water (5 mL) and filtered, the solid was washed with DMSO and MeOH then dried to give N-(1-cyanocyclopropyl)-2-(1,6-dimethyl-1H-indazol-3-yl)-5H-pyrrolo[3,2-b]pyrazine-7-carboxamide (22 mg, 23%) as a white solid. MS: (M+H)+=372; 1H NMR (300 MHz, DMSO): δ 12.98 (s, 1H), 9.14 (s, 1H), 8.95 (s, 1H), 8.55 (s, 1H), 7.58 (s, 1H), 7.25 (d, 1H, J=8.4 Hz), 4.17 (s, 3H), 2.56 (s, 3H), 1.77 (d, 2H, J=6.0 Hz), 1.48-1.44 (m, 2H).
