Procedure

(4-Iodo-phenyl)-carbamic acid tert-butyl ester (2.0 g, 6.27 mmol) was dissolved in THF (50 mL), treated with triethylamine (4.4 mL, 31.4 mmol), phenylacetylene (1.03 mL, 9.40 mmol), cuprous iodide (0.06 g, 0.31 mmol), and Pd(Ph3)2Cl2 (0.44 g, 0.63 mmol). The reaction was stirred overnight, then filtered and concentrated. The crude material was chromatographed on silica gel eluting with 7:1 hexane/EtOAc to give 1.48 g (80%) of the desired product.
