実験手順

To a high-pressure tube was added 3-bromoanisole (0.250 mL, 2 mmol), cyclopropylamine (0.225 mL, 3.2 mmol), sodium t-butoxide (0.29 g, 3.0 mmol), (+/−) BINAP (0.04 g, 0.06 mmol), and Pd2(dba)3 (0.010 g, 0.01 mmol). This mixture was suspended in 4 mL anhydrous toluene. The tube was flushed with dry nitrogen gas, then capped and wrapped in aluminum foil. The reaction mixture was stirred and heated to 80° C. overnight, then allowed to cool, and the reaction vessel was opened. The mixture was diluted with diethyl ether, filtered through Celite, and the filtrate was concentrated to a yellow oil. LC/MS analysis showed one peak with the correct mass, and due to the limited stability of the material, it was carried through without further purification. FIA MS 164 (M+1).
