実験手順

To 5.00 g (13.8 mmol) [2-(4-iodo-phenyl)-1-methyl-ethyl]-carbamic acid tert-butyl ester (I52.5) and 2.02 g (13.8 mmol) 4-ethoxyphenylacetylene in 80 mL ACN are added 4.46 mL (32.2 mmol) TEA, 135.6 mg (0.17 mmol) [1,1′-bis(diphenyl-phosphino)ferrocene]dichloropalladium(II) complex with dichloromethane and 32.3 mg (0.17 mmol) CuI, and the reaction mixture is stirred at r.t. over night. The precipitate is filtered and washed with ACN. The resulting crude product is purified by column chromatography (CyH/EtOAc 100/0→90/10).
