To a solution of 4-nitro-benzylamine (47.2 mg, 0.25 mmol) in THF (250 μL) is added triethylamine (89 μL) and ethyl sulfonyl chloride (24 μL, 0.25 mmol). The reaction mixture is shaken at ambient temperature for 16 hours. The reaction mixture is then concentrated, methanol is added followed by Novabiochem AM resin to remove unreacted amine. This is then shaken for two hours, filtered, concentrated to yield ethanesulfonic acid 4-nitro-benzylamide, which is used as such for the subsequent reaction.
