Reaction Steps

N,N-diethyl-1,4-phenylenediamine (1.00 g, 6.17 mmol) was added slowly to dilute HCl (700 μl, 32%) in H2O (100 cm3). The mixture was stirred until it was homogeneous. N-[3-(dimethylamino)phenyl]methanesulphonamide (1.32 g, 6.17 mmol) in methanol (60 cm3) was added, followed by a saturated aqueous solution of potassium dichromate (2 cm3). The mixture refluxed for 15 min. The mixture was cooled and diluted with water (200 cm3), acidified with hydrochloric acid (1M) and then extracted with chloroform (6×30 cm3). The combined extracts were dried over sodium sulphate, filtered and the solvent removed under reduced pressure. Column chromatography (1:9 methanol/dichloromethane) gave the target material as a green solid (451 mg, 22%).
