Participants

Reaction Steps

To a stirred mixture of 1-(2-methoxyphenyl)piperazine (21.34 mmol) and pyridine (25.6 mmol) in 60 mL of dry dichloromethane was added dropwise a solution of 6-bromohexanoyl chloride (23.52 mmol) in 20 mL of dichloromethane at 0° C. under nitrogen. After addition, the mixture was allowed to warm to room temperature and stirred for 1-2 hours. The mixture was quenched with 10% potassium carbonate in water, and extracted with dichloromethane. The organic phase was washed with brine and water, dried over magnesium sulfate, filtered and concentrated. The residue was purified by flash chromatography using 5% methanol, 0.5% ammonium hydroxide in ethyl acetate to give 1-(2-methoxyphenyl)-4-(6-bromohexanoyl)piperazine (6.00 g, 76%).
