Reaction Steps

To a solution of 4-chloro-6-bromoquinoline (726 mg, 3 mmol) in 3 mL of 1-methyl-2-pyrrolidinone was added piperidine (510 mg, 6 mmol). The reaction was heated to 150° C. for 5 h. The solvents were removed in vacuo at 100° C. and the residue dissolved in methylene chloride and washed with water. The methylene chloride was dried with sodium sulfate and concentrated. The residue was triturated with hexane and the solid filtered off to give 6-bromo-4-(1-piperidinyl)quinoline (877 mg, 73%).
