실험 절차

N-tert-Butyl-2-(5-(difluoromethoxy)-1H-indazol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (100 mg, 188 μmol), 3-chloro-N,N-dimethylpropanamide (25.6 mg, 188 μmol) and cesium carbonate (184 mg, 565 mmol) in dimethylformamide (2 mL) were heated in a microwave at 150° C. for 30 min. The mixture was cooled, partitioned between ethyl acetate and water, washed with water 3 times, dried and concentrated in vacuo. Purification by chromatography (silica, 24 g Analogix column, 0-100% ethyl acetate in hexanes) gave N-tert-butyl-2-(5-(difluoromethoxy)-1-(3-(dimethylamino)-3-oxopropyl)-1H-indazol-3-yl)-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamide (70 mg, 59%) as an off-white solid. MS (M+H)+=630; 1H NMR (CDCl3) δ: 9.19 (s, 1H), 8.41 (s, 1H), 8.25 (d, J=1.9 Hz, 1H), 8.08 (s, 1H), 7.67 (d, J=8.7 Hz, 1H), 7.31-7.37 (m, 1H), 6.22-6.78 (m, 1H), 5.72 (s, 2H), 4.79-4.88 (m, 2H), 3.53-3.63 (m, 2H), 3.11 (t, J=6.7 Hz, 2H), 2.95 (d, J=9.2 Hz, 6H), 1.61 (s, 9H), 0.87-1.01 (m, 2H), −0.03 (s, 9H).
