Reaction Steps

To a solution of 1-methoxy-N-triethylammoniosulfonylmethanimidate (Burgess reagent, 12.3 mmol) in THF (10 mL) at 0° C. was added 2-aminoethanol (4.91 mmol). The reaction was allowed to warm to rt and then heated to 90° C. for 8 h. After cooling to rt, the reaction was quenched with saturated aq. NH4Cl. The mixture was extracted with EtOAc and the organic layer was dried (Na2SO4) and concentrated to afford 1,1-dioxo-1λ6-[1,2,5]thiadiazolidine-2-carboxylic acid methyl ester as colorless oil that was used without further purification.
