YieldReaction ConditionsOperation in experiment
44.957% To a stirring solution of2-chloro-5-nitro-pyridine-3-carboxylic acid (10 g,49.37 mmol) in dichloromethane (200mL), oxalyl chloride (6.35 mL, 74.06 mmol) was added. DMF (g, 2.47 mmol)(three drops) was added. The solution was stirred at room temperature for five hours until no bubble from solution was seen. 3- methylsulfonylanibne (10.14 g, 59.24 mmol) was added. N,N-diisopropylethylamine (17.72 mL, 98.74 mmol) was added to the solution dropwise. The solution was stirred at room temperature for one hour. DCM (200 mL) was added, and the solution was extracted with hydrochloric acid solution (1N, 2 X 100 mL), brine(l00 mL), and then dried over sodium sulfate. The solution was filtered and concentrated. The residue was purified by silica gel chromatography, eluting with ethyl acetate/heptane(30- 100% gradient) to give 2-chloro-N-(3-methylsulfonylphenyl)-5-nitro-pyridine-3- carboxamide (11.28 g, 22.195 mmol, 44.957% yield) as purple solid. MS, ES+m/z 356.0 [M+H]+. NMR (400 MHz, CHLOROFORM-d) d ppm 3.02 - 3.11 (m, 3 H) 7.60 - 7.82 (m, 3 H) 7.94 - 8.05 (m, 1 H) 8.61 (d, J=2.78 Hz, 1 H) 9.22 - 9.31 (m, 1 H).
