To a suspension of resin-bound (2aminoethyl)(5-nitro(2-pyridyl))amine (30 g, 21 mmol), CH2Cl2 (250 mL) and iPr2NEt (18.3 mL, 105 mmol) at 23° C. was added 2-nitrobenzenesulfonyl chloride (23.3 g, 105 mmol). The resulting mixture was shaken at 23° C. for 6 h, filtered, washed with NMP, H2O and CH2Cl2 and air dried to yield polymer-bound {2-[(5-nitro(2-pyridyl))amino]ethyl}[(2-nitrophenyl)sulfonyl]amine.
