Reaction Steps

To a solution of 5-bromo-2-dimethylamino-4-ethoxy-benzonitrile (1.95 g, 7.3 mmol) in 7.25 mL of dioxane was added sodium methoxide (581 mg, 10.77 mmol), methyl formate (1.85 mL, 30 mmol), and trans-dichlorobis(triphenylphosphine) palladium(II) (281 mg, 0.4 mmol). The mixture was agitated by bubbling nitrogen gas through the solution. To the opening of the vial is affixed a balloon. The reaction was cautiously warmed to 60° C. as gas evolution can cause a froth to enter the balloon. The reaction mixture was stirred for 20 h at 65° C. It was diluted with dioxane and stirred for an additional 5 min. The warm solution was filtered through Celite, and the filtrate was concentrated in vacuo. Purification of the crude residue by flash column chromatography (silica gel, eluting with a gradient of ethyl acetate in hexanes) gave cyano-4-dimethylamino-2-ethoxy-benzoic acid methyl ester (218 mg, 12%).
