Reaction Steps

In an ice bath under argon flow, a solution of 1.07 M phenylmagnesium bromide in THF (33.2 mL) was added dropwise to a solution of 2-benzyl-1-phenyl-3,4-dihydroisoquinoline hydrobromate (8.95 g) in THF (80 mL) over 1 hour. The mixture was stirred at room temperature for 1 hour. A saturated aqueous ammonium chloride solution was added to the mixture which was then extracted with EtOAc. The extract was washed with water and saturated brine, dried over magnesium sulfate, and filtered. The filtrate was concentrated under reduced pressure, and the resulting residue was purified by silica gel column chromatography (hexane-EtOAc) to obtain 2-benzyl-1,1-diphenyl-1,2,3,4-tetrahydroisoquinoline (1.81 g).
