실험 절차

9.4 ml (0.244 mol) of methanesulfonyl chloride are metered over 30 minutes with ice-cooling to a solution of 30.1 g (0.122 mol) of 3-nitro-4-methoxycarbonyl-benzylammonium chloride and 34 ml (0.244 mol) of triethylamine in 300 ml of dichloromethane, and stirring of the mixture is continued for one hour. For work-up, the reaction mixture is treated with ice water, the phases are separated, and the aqueous phase is reextracted twice more with dichloromethane. After drying (Na2SO4), filtration and concentration, 31.3 g (89%) of methyl 4-methanesulfonylaminomethyl-2-nitrobenzoate remain as a syrupy oil.
