Procedure

A solution of methyl 3-[bis(2-hydroxyethyl)amino]-2,6-dinitrobenzoate [Palmer et al., J. Med. Chem. 1996, 39, 2518] (7.24 g, 22 mmol) in CH2Cl2 (120 mL) was cooled in an ice-bath and Et3N (15 mL) and MsCl (8 mL) were added in one portion. After stirred for 10 min, satd. NaHCO3 (100 mL) was added, and after a further 30 min the aqueous phase was extracted with CH2Cl2 (2×70 mL), the combined organic phase were dried, concentrated under reduced pressure, and the residue was purified by column chromatography on silica gel. Elution with EtOAc/petroleum ether (1:1 to 1:0), gave crude methyl 3-(bis{2-[(methylsulfonyl)oxy]ethyl}amino)-2,6-dinitrobenzoate (16) (10.67 g, 100%) as a yellow oil;
