Benzoic acid, 2-(chlorosulfonyl)-, methyl ester → HCID 58924311, compound

Participants

Reaction Steps

To a solution of 5-methoxypyridin-3-amine (1 eq) in pyridine (0.4 M) was added methyl 2-(chlorosulfonyl)benzoate (1 eq) and the mixture was stirred overnight at room temperature. The mixture was 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 afford the title compound. 1H NMR (400 MHz, DMSO-D6) δ ppm 10.56-10.66 (m, 1H) 8.55-8.61 (m, 1H) 7.95-8.01 (m, 1H) 7.86-7.94 (m, 1H) 7.67-7.73 (m, 2H) 7.34-7.40 (m, 1H) 7.02 (s, 1H) 3.83 (s, 3H) 3.73 (s, 3H).
