Reaction Steps

A solution of 0.5 g. (0.0017 mole) of ethyl 5-(p-cyanobenzoyl)-1-methylpyrrole-2-acetate in 3 ml. ethanol is brought to reflux and 1.7 ml. of 1N sodium hydroxide solution is added dropwise. The mixture is refluxed for 3 minutes, and the ethanol is then evaporated in vacuo. The residue is diluted with water and acidified with dilute hydrochloric acid.
