Participants

Reaction Steps

A mixture of 1-(2-nitro-phenyl)-piperazine (4.53 g) (commercially from Emkachem) and 3,4-dichlorobenzyl bromide (4.6 g) in 100 mL of dichloromethane was treated with triethylamine (3.4 mL). The reaction was stirred at ambient temperature under inert atmosphere overnight. After solvent removal, the crude reaction mixture was subjected directly to flash chromatography using silica. Elution with hexanes, then 20% ethyl acetate in hexanes, and finally 33% ethyl acetate in hexanes furnished the product as an oil (6.4 g), which was carried on as is.
