Chloromethyl Methyl Ether → 5-Chloro-3-[methoxymethyl-(4-chloro-3-trifluoromethyl-benzenesulfonyl)-amino]-pyridine-2-carboxylic acid methoxymethyl-amide

Participants

Reaction Steps

To a suspension of sodium hydride (314 mg, 7.86 mmol) in 8 mL of THF was added a mixture of 5-chloro-3-(4-chloro-3-trifluoromethyl-benzenesulfonylamino)-pyridine-2-carboxylic acid methoxy-methyl-amide (3.0 g, 6.55 mmol) and chloromethyl methyl ether (0.741 mL, 9.825 mmol) in 8 mL of THF. The mixture was stirred at room temperature overnight. After the removal of the solvents the residue was purified by flash column (20% ethyl acetate in hexane) to afford 2.70 grams of the title compound as a white solid. (M+H)+ expect 502.0, found 502.0.
