Reaction Conditions

Reaction Steps

A mixture comprising 8.00 g of methyl N-(5-bromo-2-fluorobenzyl)carbamate, 4.50 g of trimethylsilylacetylene, 0.96 g of dichlorobis(triphenylphosphine)palladium, 0.47 g of copper(I) iodide and 30 ml of triethylamine, was stirred at 90° C. for 48 hours in an autoclave. This reaction solution was poured into a saturated sodium chloride aqueous solution and extracted with ethyl acetate, followed by drying over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography to obtain 7.09 g of methyl N-[2-fluoro-5-(trimethylsilylethynyl)benzyl]carbamate as a brown viscous liquid.
