Procedure

A solution of 3 g (4.5 mmol) of N{{3-{3[- 4-acetyl-3-hydroxy-2-(3,3,3-trifluoropropyl)-phenoxy}-propoxy}-4-chloro-6-methyl-phenyl}}-1-(4-methoxybenzyl)-tetrazole-5-carboxamide in 90 ml of trifluoroacetic acid and 9 ml of anisole is refluxed for 60 minutes. The reaction mixture is concentrated under reduced pressure, about 150 ml of ether and 300 ml of petroleum ether are added and the crystals are filtered off. The N-{{3-{3-[4-acetyl-3-hydroxy-2-(3,3,3-trifluoropropyl)-phenoxy]-propoxy}-4-chloro-6-methyl-phenyl}}-1H-tetrazole-5-carboxamide thus obtained, of melting point 236°-238° (decomposition) is dissolved in 50 ml of tetrahydrofuran, and one equivalent of sodium, dissolved in 5 ml of methanol, is added. After addition of ether, crystallisation starts. The sodium salt of N-{{3-{3-[4-acetyl-3-hydroxy-2-(3,3,3-trifluoropropyl)-phenoxy]-propoxy}-4-chloro-6-methylphenyl}}-1 H-tetrazole-5-carboxamide of melting point 9020 (decomposition) is thus obtained.
