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 14 h 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%).
