실험 절차

To a solution of N-(4-bromophenyl)-N-(1-phenylmethylidene)amine (1.0 g, 0.00385 mol) in toluene (30 mL) cooled to −78° C., a 1.4M solution of methyl lithium in diethyl ether (5.5 mL) was added dropwise keeping the temperature below −75° C. The solution was warmed up to −40° C. and stirred at this temperature under an atmosphere of nitrogen for 3 hours. The reaction mixture was quenched by a dropwise addition of water and the layers were separated. The organic phase was washed with brine (50 mL), dried with magnesium sulfate and concentrated under reduced pressure to yield N-(4-bromophenyl)-N-(1-phenylethyl)amine (1.03 g, 0.00373 mol) as an off-white solid.
