Reaction Steps

A solution of 5-phenyl-[1,3,4]oxathiazol-2-one (30.33 mmol) and dimethylacetylenedicarboxylate (60.67 mmol) in chlorobenzene (17.8 mL) was refluxed with stirring for 6 h before it was concentrated in vacuo. The residue was crystallized from cold MeOH to give the title compound (5.0 g) as a slightly yellow solid: MS (m/z) 278.1 (M+1).
