Reaction Steps

To a solution of 5-methylpyridin-3-amine (0.5 g, 4.62 mmol) in CH2Cl2 (50 ml) were added triethylamine (0.64 mL, 4.62 mmol) and methyl 2-(chlorosulfonyl)benzoate (1.08 g, 4.62 mmol). The resulting mixture was stirred at room temperature for 1 hour. The mixture was then diluted with saturated aqueous NaHCO3 and extracted with CH2Cl2. The organic layer was dried over Na2SO4, filtered and concentrated. The crude residue was purified by flash chromatography (0-8% MeOH/CH2Cl2) to give the title compound (0.476 g, 34%). 1H NMR (400 MHz, DMSO-D6) δ ppm 10.25-10.62 (m, 1H) 8.6 (s, 2H) 7.81-7.93 (m, 1H) 7.64-7.76 (m, 2H) 7.54-7.64 (m, 1H) 7.28 (s, 1H) 3.80 (s, 3H) 2.18 (s, 3H).
