反応手順
10 g (0.58 mole) of 2-nitrophenylsulfonamide are suspended in 20 ml of toluene and heated to reflux temperature. 17.0 g (0.087 mole) of diisopropyl aminomethylphosphonate are added dropwise to the hot solution. The reaction mixture is then boiled under reflux for 10 hours, cooled and evaporated. Chromatographing the residue over silica gel with a 4:1 methyl acetate/hexane mixture gives 1.6 g of 2-(di-i-propoxyphosphonylmethylamino)-phenylsulfonamide in the form of a yellow oil.
