الإجراء التجريبي
470 mg (1.27 mmol) of ethyl 1-methyl-4-[({[4-(trifluoromethoxy)phenyl]amino}carbonyl)amino]-1H-pyrrole-2-carboxylate are initially charged in 5 ml of THF, 152 mg (6.33 mmol) of lithium hydroxide in 1 ml of water are added and the mixture is stirred under reflux overnight. The reaction mixture is concentrated, the residue is acidified with 2M hydrochloric acid and the precipitate formed is filtered off with suction and dried under reduced pressure. This gives a solid.
