반응 단계

Benzyl cyanide (0.97 mL, 8.4 mmole) was reacted with lithium bis(trimethylsilyl)amide (LHMDSA) (8.4 mL, 8.4 mmole) in 5 mL of THF at -78° C. for 1 hour. After an additional aliquot of LHMDSA (4.2 mL, 4.2 mmole) was added, N-(2-chloroethyl)dibenzylamine hydrochloride (1.0 g, 3.4 mmole) was then added. The reaction was allowed to stand at room temperature and was then warmed to 50° C. for 3.5 hours. The mixture was poured into ice/water, and the product was extracted with ethyl acetate. The ethyl acetate layer was washed with brine, dried over sodium sulfate and concentrated under reduced pressure to afford alpha-(N,N-dibenzylaminoethyl) benzyl cyanide (1.05 g), isolated in 94% yield (MS: (M+H)+ =341).
