(E)-N-(4-Bromophenyl)-1-(1H-pyrrol-2-yl)methanimine (136 mg, 545 μmol, 1.20 equiv) was deprotonated using a stoichiometric amount of tBuOK (61.2 mg, 545 μmol, 1.20 equiv) in 5 mL of dry DCM. The reaction was stirred for four hours, then the mixture was transferred to a solution containing CuCl (45.0 mg, 455 μmol, 1.00 equiv) and DPEPhos (245 mg, 455 μmol, 1.00 equiv) in 3 mL of dry DCM. The reaction was stirred for 18 hours at 20 °C then the salt was filtered off, and the solvent was evaporated under reduced pressure to afford an oil that was treated with 5 mL of pentane. The product was filtered off, washed with 2x5 mL of pentane and dried in vacuo to afford a dark yellow solid (274 mg, 322 μmol, 71% yield).
