Reaction Steps

Methyl 5-(methoxymethyl)-1,2,3-thiadiazole-4-carboxylate (4.18 g, 0.022 mol) was dissolved in carbon tetrachloride (60 mL). To the solution was added bromine (4.18 g, 0.026 mol) and the solution was refluxed upon irradiation with long wavelength UV light (100 watts) for 3 h. The volatiles were evaporated in vacuo and the crude material purified by flash chromatography to give the desired product (2.70 g, 71%) as a viscous oil. 1H NMR (400 MHz, CDCl3): δ□ 10.67 (s, 1H), 4.15 (s, 3H). MF=C5H4N2O3S; LCMS calculated for C5H5N2O3S (M+H)+: m/z=173.0.
