2-Ethoxy-4-iodopyridine → N-{2-[4-(2-Ethoxy-pyridin-4-ylethynyl)-phenyl]-1-methyl-ethyl}-acetamide

Participants

Reaction Steps

To 100 mg (0.50 mmol) N-[2-(4-ethynyl-phenyl)-1-methyl-ethyl]-acetamide (I58.2) and 124 mg (0.50 mmol) 2-ethoxy-4-iodo-pyridine (I6.1) in 5.00 mL ACN are added 20.3 mg (0.03 mmol) 1,1′-bis[diphenylphosphino]ferrocenepalladium dichloride dichloromethane complex (1:1), 4.83 mg (0.03 mmol) CuI and 0.16 mL (1.16 mmol) TEA. The mixture is stirred at r.t. over night, then poured onto water and extracted with DCM. The organic layer is dried with MgSO4 and the solvent is removed in vacuo. The residue is purified by column chromatographie (silica gel; PE/EtOAc 1/1→EtOAc 100%).
