Trifluoroacetic acid → 5-(6-Bromo-naphthalen-2-yl)-2-pyrrolidin-2-yl-1H-imidazole

Participants

Reaction Steps

2-[5-(6-Bromonaphthalen-2-yl)-1H-imidazol-2-yl]-pyrrolidine-1-carboxylic acid tert-butyl ester (5.03 g) was dissolved in dichloromethane (75 mL), and trifluoroacetic acid (25 mL) was added. The reaction mixture was stirred at ambient temperature for 5 hours and evaporated under vacuum. Solid was dissolved in dichloromethane (50 mL) and extracted with saturated NaHCO3 solution (50 mL) Solid was collected by vacuum filtration, washed with dichloromethane, and dried under vacuum, giving 5-(6-Bromo-naphthalen-2-yl)-2-pyrrolidin-2-yl-1H-imidazole (98%) as an off-white solid.
