Conditions

Temperature: 60 °C

Procedure

A two necked flask was charged under argon with rhodium(acac)bis ethylene (185 mg, 0.05 eq.), (R)-BINAP (442 mg, 0.05 eq.) and 4-fluoro-phenylboronic acid (4.87 g, 2.5 eq.). 300 mL of MeOH and 30 mL of H2O were added followed by 1-(1-benzyl-2,5-dihydro-1H-pyrrol-3-yl)-ethanone (2.8 g). The reaction mixture was heated at 60° C. for 8 hours, cooled down to RT and concentrated under vacuo. Purification by flash chromatography (SiO2, EtOAc/Heptane 2/1) afforded 0.40 g (10%) of the title product as a light yellow oil. ES-MS m/e: 298.2 (M+H+).
