Reaction Steps

5-Cyano-4-hydroxymethyl-3-methyl-isothiazole (50% purity) (1.14 g, 3.7 mmol) was dissolved in dichloromethane (10 ml) and triphenyl phosphine (1.07 g, 4.0 mmol) and carbon tetrabromide (1.18 g, 3.6 mmol) were added at 0° C. The mixture was stirred at 0° C. for 2 hours, concentrated and the crude product was purified by chromatography on silica gel (eluent: ethyl acetate/hexane). The colourless oil (0.65 g) consisted of a 1:1 mixture of methyl ester (see Example I14) and product. The mixture was used without further purification.
