Procedure

36.6 g (0.187 mole) of ethyl 3-amino-1,4,5-trimethyl-1H-pyrrole-2-carboxylate and 11.4 g (0.213 mole) of potassium hydroxide are dissolved in 200 ml of methanol, and the obtained solution is boiled under reflux for 4 hours. The resulting solution is concentrated to dryness and used, without further purification, for the next reaction.
