Bromination of 2-[2-(5-nitro-2-furyl)vinyl]benzothiazole gave 2-[1-bromo-2-(5-nitro-2-furyl)vinyl]benzothiazole which was dehydrohalogenated with dimethylformamide and potassium hydroxide to obtain 2-[2-(5-nitro-2-furyl)ethynyl]benzothiazole. The usual method of using methanol and potassium hydroxide in this case afforded 2-[2-methoxy-2-(5-nito-2-furyl)vinyl]benzothiazole.
