실험 절차

To a stirred solution of 2-(6-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (100 mg, 0.34 mmol), DCI (123 mg, 0.64 mmol) and DMAP (110 mg, 0.90 mmol) in 6 mL of DMF was added N1,N1,2-trimethylpropane-1,2-diamine (100 mg, 0.86 mmol) in one portion at room temperature, then the mixture was stirred for 16 hours. The reaction mixture was poured into 40 mL of water, filtered and the filter cake was purified by column chromatography (silica gel, 200-300 mesh, eluting with a mixture of methanol and THF (1:3, v/v) to give N-(1-(dimethylamino)-2-methylpropan-2-yl)-2-(6-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (22 mg, 16.5%) as a yellow solid. MS: (M+H)+=392; 1H NMR (300 MHz, DMSO): δ 13.38 (s, 1H), 12.90 (brs, 1H), 9.15 (s, 1H), 8.47 (d, 1H, J=8.4 Hz), 8.37 (s, 1H), 7.97 (s, 1 h), 7.45 (s, 1H), 7.10 (d, 1H, J=8.4 Hz), 2.74 (s, 2H), 2.52 (s, 3H), 2.29 (s, 3H), 2.26 (s, 3H), 2.01 (s, 6H).
