실험 절차

A solution of 2-pyridin-2-yl-4-methyl-pyrimidine-5-carboxylic acid (1.69 mmol), 5-methoxy-3-methyl-pyrrolo[3,2-b]pyridin-1-ylamine (1.69 mmol), DIPEA (5.01 mmol) and HATU (2.03 mmol) in anhydrous DMF (8 mL) is stirred at 90° C. for 16 h. DMF is evaporated in vacuo. The residue is dissolved in EtOAc (40 mL), and washed with water (3×10 mL) and brine (10 mL). The organic layer is dried (Na2SO4), filtered, and concentrated in vacuo. The residue is purified by silica gel column chromatography eluting with 0-15% MeOH in DCM to afford 4-methyl-2-pyridin-2-yl-pyrimidine-5-carboxylic acid (5-methoxy-3-methyl-pyrrolo[3,2-b]pyridin-1-yl)-amide (295 mg) as a solid. MS: 375 (M+H); 1H NMR (300 MHz, CD3OD): δ 2.40 (s, 3H), 2.84 (s, 3H), 4.02 (s, 3H), 6.70 (d, H), 7.13 (s, H), 7.41 (m, H), 7.50 (d, H), 7.85 (t, H), 8.51 (m, 2H), 8.78 (s, 2H), 10.57 (br, N—H).
