Reaktionsschritte

An oven dried test tube was charged with Pd2(dba)3 (4.5 mg, 0.005 mmol), 27 (7.4 mg, 0.015 mmol), 4-chloroanisole (140 mg, 0.98 mmol), pyrrolidine (85 mg, 1.2 mmol), NaOt-Bu (135 mg, 1.4 mmol), toluene (2 mL), and purged with argon. The mixture was heated to 80° C. and stirred for 18 hours. The reaction mixture was cooled to room temperature, diluted with ether (5 mL), filtered through a plug of celite, and concentrated in vacuo. The residue was purified by flash chromatography on silica gel to give 165 mg (95%) of the title product as colorless crystals.
