Versuchsvorschrift

A solution of 393 mg of isopropyl 4-(1-hydroxy-1-methylethyl)-2-isopropoxymethyl-1-{4-[2-(tetrazol-5-yl)phenyl]phenyl}methylimidazole-5-carboxylate [prepared as described in Example 92(b)] in 3 ml of a 1N aqueous solution of sodium hydroxide was stirred at room temperature for 2 hours, and then insoluble matter was filtered off. 3 ml of 1N aqueous hydrochloric acid were added to the filtrate, and the precipitated amorphous powder was collected by filtration, to give 325 mg of the title compound, melting at 153°-161° C. (with softening).
