Reaction Steps

A mixture of 35 g of 4-chloro-1,2-dinitrobenzene and 20 g of 1-amino-4-methylpiperazine in 200 ml of 96° EtOH is stirred for 24 hours at RT. The reaction mixture is evaporated under vacuum and the residue is chromatographed on silica using a DCM/AcOEt mixture (80/20; v/v) as the eluent to give 17.5 g of the expected product after crystallization from an iso ether/heptane mixture (50/50; v/v). M.p.=108° C.
