Reaction Steps

5-bromo-2-methoxypyridin-3-amine (1.231 mmol) was dissolved in pyridine (3 ml) at 0° C. Benzene sulfonyl chloride (1.847 mmol) was added drop wise and the reaction mixture was stirred at RT for 2 h. The reaction mixture was evaporated to dryness and the residue was dissolved in ethyl acetate (100 mL). The ethyl acetate layer was washed with water, separated and dried over sodium sulfate. The organic layer was evaporated to dryness. The crude material obtained was purified by (silica column, EtOAc/Hexane as eluent) to obtain the title compound. 1HNMR (300 MHz, DMSO-d6): δ 10.16 (s, 1H), 8.05 (d, J=2.4 Hz, 1H), 7.77 (m, 2H), 7.68 (d, J=2.4 Hz, 1H), 7.64 (m, 1H), 7.55 (m, 1H), 3.61 (s, 3H); MS (m/z): 343 (M)+.
