Procedure

40 mg 2-[(1-Bromo-naphthalene-2-carbonyl)-amino]-2-methyl-propionic acid methyl ester and 2 mg Bis(triphenylphosphine)palladium(II) chloride were suspended in 2 ml of DMF and deoxygenated with Argon. 0.26 ml of TMEDA were added, the mixture was again bubbled with Argon, and then 14 mg (0.137 mmol) phenylacetylene were added. After 14h at 80° the reaction was filtered, purified by RP-HPLC and freeze-dried to give 8 mg of 2-{[1-(Phenylethynyl)-naphthalene-2-carbonyl]-amino}-2-methyl-propionic acid methyl ester (19%).
