General Procedure for Catalytic Experiments
General procedure: K3PO4 (5.62 mmol) in DMSO (4 mL), were added Cu(OAc)2 (0.28 mmol). The flask was evacuatedand backfilled with argon for three times. The resulting suspension was heated in a 80 °C oil bathwith stirring for the indicated time. The reactor was cooled to r.t., the flask was opened to air and thereaction mixture was poured into water (20 mL), extracted with ethyl acetate (20 mL × 3), andorganic layer was washed with water (20 mL × 2) and once with brine (25 mL), dried overmagnesium sulfate and concentrated in vacuo. The product was purified by column chromatographyon silica gel using petroleum ether and ethyl acetate as eluent.1-(2-Methoxyphenyl)-1H-pyrrole (3a) [30]: colorless oil (0.43 g, 88%). 1H-NMR (400 MHz, CDCl3) δ (ppm):7.30-7.23 (2H, m), 7.03-6.98 (4H, m), 6.30 (2H,
