Reaction Steps

A solution of ethyl[3-methoxy-4-(5-nitropyridin-2-yloxy)phenylamino]acetate (2.43 g, 7.00 mmol) was dissolved in THF (15 mL), dichloromethane (20 mL) and DMF (10 mL), and to the resulting solution were added triethylamine (1.95 mL, 13.99 mmol), 4-dimethylaminopyridine (0.86 g, 7.00 mmol) and methanesulfonyl chloride (1.08 mL, 13.99 mmol) under ice cooling. The resulting solution was stirred for 14 hours at 30° C. Water was added to the reaction mixture, and extracted with dichloromethane. The dichloromethane layer was washed with water and brine. The dichloromethane layer was dried over anhydrous magnesium sulfate, evaporated, and the residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=1:2), to thereby yield 1.10 g of the title compound.
