Procedure
Sodium hydroxide (64 g) was added to a solution of hydroxylamine hydrochloride (111 g) in water (370 ml) and the obtained solution was diluted with ethanol (3500 ml). N-(4-benzoyl-1,5-dimethyl (1H)pyrrol-3-yl)-2-iodoacetamide (124.5 g) was then added and the obtained suspension was stirred under nitrogen stream for about 48 hours. The reaction mixture was filtered in order to remove the salts and the filtrate was concentrated to dryness at the pump. The residue was washed with a small amount of water and crystallized from ethyl acetate yielding 82.5 g of the compound of the title. M.p. 140°-42° C.
