Versuchsvorschrift

A mixture of 1-(2-diethylaminoethyl)-4-trifluoromethyl-6-iodo-3-hydroxy-3-(2-chlorophenyl)oxindole (796 mg, 0.144 mmol), 3-(2-oxo-1,3-oxazolin-3-yl)-1-propyne (464 mg, 0.371 mmol), CuI (10.8 mg, 0.0567 mmol), and (PPh3)2PdCl2 (18.6 mg, 0.0265 mmol) in triethylamine (1 mL) was stirred for 4.5 h at 50° C. Water and sat. aqueous NaHCO3 were added and the mixture was extracted with ethyl acetate. The extracts were dried over MgSO4 and concentrated. The residue was purified by silica gel column chromatography with 80:1 to 50:1 chloroform/methanol to give the title compound (738 mg). The compound was dissolved in dioxane (2 mL) and 4 N HCl in dioxane (1 mL) was added. The solvent was evaporated azeotropically with toluene. The residual solid was washed with ether and dried in vacuo to give the hydrochloride (528 mg, 63%).
