At ambient temperature 0.20 ml methanesulphonic acid chloride are added dropwise to a solution of 0.48 g 1,3-diamino-5-tert-butyl-2-isopropoxy-benzene and 0.35 ml of pyridine in 5 ml dichloromethane. The solution is stirred for 2 h at ambient temperature and then evaporated down. The residue is chromatographed on silica gel with cyclohexane/ethyl acetate (90:10→40:60) as eluant.
