Procedure

To a mixture of EXAMPLE 242B (3.0 g), bis(triphenylphosphine)palladium(II) dichloride (242 mg), CuI (66 mg) in triethylamine (30 mL) was added trimethylsilylacetylene (2.2 g). The mixture was stirred at room temperature overnight. The mixture was diluted with ethyl acetate (200 mL) and washed with aqueous NH4Cl, water, brine and dried over Na2SO4. The mixture was filtered, and the solvent was evaporated and the residue was loaded on a column and eluted with 10% ethyl acetate in hexane to give the pure product.
