A mixture of 6.0 g of 2-(trans-3-hydroxystyryl) benzothiazole and 0.5 g of 5% palladium-carbon in 80 ml of ethanol was stirred under hydrogen gas stream under normal pressure at 50° to 60° C. for 3 hours. After completion of the reaction, the catalyst was filtered off and the filtrate was evaporated under reduced pressure to obtain 5.5 g (yield 92%) of the title compound as pale gray crystals.
