Reaction Steps

Under protective argon gas a mixture of 235 mg (0.64 mmol) ethyl (R)-2-amino-3-(4-amino-3-chloro-5-iodo-phenyl)-propionate, 45.9 mg (0.064 mmol) bis-(triphenylphosphine)-palladium(II)-dichloride, 6.0 mg (0.032 mmol) copper(I)- iodide and 15 ml triethylamine was combined with 0.19 ml (1.32 mmol) trimethylsilylacetylene and stirred for 3 hours at ambient temperature. The reaction mixture was combined with 30 ml of water and extracted with 40 ml of ethyl acetate. The organic phase was dried over sodium sulphate, evaporated down under reduced pressure and the residue was purified by column chromatography through silica gel.
