Allyl bromide → HCID 10319122, compound

Participants

Reaction Steps

To a solution of N,N-diethyl-4-[benzyl(piperidin-4-yl)amino]benzamide (Compound 8) (0.25 g, 0.684 mmole) in 10 mL of acetonitrile was added potassium carbonate (0.10 g, 0.752 mmole) and allyl bromide (0.08 g, 0.684 mmol). The reaction mixture was stirred for six days under Argon and then was diluted with water (50 mL). This solution was extracted three times with dichloromethane (50 mL). The organic extracts were combined, washed with sodium carbonate solution, dried (Na2SO4), and concentrated to provide a yellow foam. This material was purified on a flash silica gel column (5% methanol-chloroform to 10% methanol-chloroform) to provide 0.11 g (40%) of N,N-diethyl-4-[benzyl(1-allylpiperidin-4-yl)amino]benzamide as a colorless oil.
