Procedure

42 microliters of mesyl chloride are added to a solution of 160 mg of 2-{1-methyl-4-[4-nitro-3-(propan-2-yloxy)phenyl]piperazin-2-yl}ethanol in 2 ml of dichloromethane and 0.2 ml of pyridine. The reaction medium is stirred at ambient temperature overnight and then concentrated under vacuum, under reduced pressure, so as to give 190 mg of 2-{1-methyl-4-[4-nitro-3-(propan-2-yloxy)phenyl]piperazin-2-yl}ethyl methanesulfonate in the form of an orangey-coloured oil.
