Procedure

10.6 g (28.1 mmol) of ethyl 4-({[(4-chloro-2-methylphenyl)amino]carbonyl}amino)-1-(cyclopropylmethyl)-1H-imidazole-2-carboxylate are suspended in 158 ml of ethanol. While cooling in ice, 16.4 ml of water and 6 ml (112 mmol) of 50% strength aqueous sodium hydroxide solution are added. The reaction mixture is stirred at room temperature for 1 h and then concentrated in vacuo. The residue is taken up in 100 ml of isopropanol and, while cooling in ice, 100 ml of 1N hydrochloric acid are added. The crystals are filtered off with suction and dried in vacuo at 40° C.
