To the resulting mixture PdCl2 (1.21 g, 9.6 mmol, 0.23 equiv) was added and the mixture was stirred under nitrogen for 45 h. The resulting mixture was extracted with EtOAc (3×100 ml). The combined extracts were washed with 5% HCl, brine, dried over MgSO4 and concentrated under vacuum. The residue was purified by column chromatography (EtOAc:hexane 70:30) to give 3-(4′-Acetamidophenyl)-1-propanal (1.92 g, 23.1%) which was used as such in the next step. the mixture was stirred under nitrogen for 45 h The resulting mixture was extracted with EtOAc (3×100 ml) The combined extracts were washed with 5% HCl, brine dried over MgSO4 concentrated under vacuum The residue was purified by column chromatography (EtOAc:hexane 70:30)
