Procedure

0.70 g (0.98 mmol) of 2-butyl-4-chloro-1-{[2-[2-[2-(triphenylmethyl)-2H-tetrazol-5-yl]phenyl]quinolin-6-yl]methyl}-1H-imidazole-5-carbaldehyde obtained in Example 8 was suspended in 12 ml of methanol. 12 ml of concentrated hydrochloric acid was added thereto while in an iced water bath followed by stirring at room temperature for 24 hours. The reaction mixture was iced and alkalized with a 10N sodium hydroxide solution. After adding 10 ml of water thereto, the mixture was filtered and the filtered cake was washed with 10 ml of a 1N sodium hydroxide solution. The filtrate was acidified by adding concentrated hydrochloric acid dropwise thereto and extracted with 100 ml of ethyl acetate. The organic layer was dried over magnesium sulfate and filtered. The filtrate was concentrated to obtain 0.102 g of 2-butyl-4-chloro-1-{[2-[2-(1 H-tetrazol-5-yl)phenyl]-quinolin-6-yl]methyl}-1H-imidazole-5-carbaldehyde.
