実験手順

To a solution of methyl 3-iodo-4-acetamido-5-chlorosalicylate (2 g) in distilled Et3N (60 ml) and dioxane (40 ml), trimethylsilylacetylene (1 ml), CuI (23 mg), and PdCl2 (PPh3)2 (152 mg) were added. The reaction mixture was stirred at 40° C. for 1.5 hours, after which time the solvents were removed in vacuo. A sample of the residue was purified by column chromatography for analytical purposes eluting with diethyl ether/hexane mixtures to yield the intermediate methyl 3-trimethylsilylethynyl-4-acetamido-5-chloro-salic ylate.
