Reaction Steps

A mixture of 25 g of methyl 3-acetylamino-4,5-dichlorothiophene-2-carboxylate, about 10 g of triethylamine, 300 ml of methanol and 1 g of palladium on carbon is, at room temperature and under atmospheric pressure, hydrogenated until the uptake of hydrogen has stopped. The catalyst is filtered off and the mixture is then concentrated by distillation under reduced pressure until crystallization begins, water is then added and the solid is filtered off. Colorless crystals from isopropanol. M.p. 142-147° C.
