Reaction Steps

A mixture of methyl(2,5-dichloro-1H-pyrrol-1-yl)acetate (0.5 g), in ether (3 cm3), and concentrated aqueous ammonia solution (3 cm3) was stirred at room temperature overnight in a stoppered flask. The precipitated crystalline product was collected by filtration and washed with ether to give 0.07 g of title compound. The ethereal washings were dried and evaporated. The crystalline residue was triturated with diisopropyl ether to give a further 0.13 g of title compound, m.p. 183°-4° C.
