実験手順

An oven-dried resealable Schlenk tube was purged with argon and charged with Pd2(dba)3 (2.3 mg, 0.0025 mmol, 1.0 mol % Pd), 2 [Example 1] (3.0 mg, 0.0076 mmol, 1.5 mol %), K3PO4 (150 mg, 0.71 mmol), and methyl 4-bromobenzoate (108 mg, 0.50 mmol). The tube was purged with argon, fitted with a rubber septum and then DME (1.0 mL) and morpholine (55 μL, 0.63 mmol) were added. The septum was removed, the tube was sealed with a teflon screw cap and the mixture was stirred at 80° C. for 24 h. The reaction mixture was then cooled to room temperature, diluted with EtOAc (20 mL), filtered through celite and concentrated in vacuo. The crude material was purified by flash chromatography on silica gel to afford 89 mg (80%) of a colorless solid.
