실험 절차

A slurry of aluminum trichloride (0.270 g, 2.03 mmol) was added to a slurry of 2,6-difluoro-3-(propylsulfonamido)-N-(1H-pyrrolo[2,3-b]pyridin-5-yl)benzamide (0.100 g, 0.254 mmol) in DCM (0.7 mL) at 0° C., and the reaction mixture was allowed to stir at 0° C. for 40 minutes. Acetyl chloride (0.0271 mL, 0.380 mmol) was added, and the mixture was allowed warm to room temperature overnight. CH3NO2 (200 μL) was added, and the reaction mixture was sonicated for 2 minutes, and allowed to stir at room temperature overnight. The reaction mixture was quenched with ice and then partitioned between aqueous sodium bicarbonate and EtOAc. The organic layer was dried over Na2SO4 and concentrated under reduced pressure. The resulting residue was purified via column chromatography (5% MeOH/EtOAc) to yield N-(3-acetyl-1H-pyrrolo[2,3-b]pyridin-5-yl)-2,6-difluoro-3-(propylsulfonamido)benzamide (71 mg, 64%) as a solid. 1H NMR (400 MHz, CDCl3) δ 8.98-8.99 (m, 1H), 8.63-8.64 (m, 1H), 8.04 (s, 1H), 7.49-7.54 (m, 1H), 7.15-7.18 (m, 1H), 3.10-3.30 (m, 2H), 2.55 (s, 3H), 1.93-2.00 (m, 2H), 1.09-1.13 (m, 3H); m/z (APCI-pos) M+1=437.1.
