Procedure

A suspension of 1.75 g (3 mmol) of methyl N-{{3-{3-[4-acetyl-3-hydroxy-2-(3,3,3-trifluoropropyl)-phenoxy]-propoxy}-4-bromo-6-methyl-phenyl}}-oxamate (Example 2) in 30 ml of methanol and 3.2 ml of N sodium hydroxide solution is refluxed for 60 minutes. The reaction mixture is concentrated under reduced pressure, the residue is dissolved in acetone and dilute sodium hydroxide solution and the solution is acidified with dilute hydrochloric acid. The product which has precipitated is filtered off and washed neutral with water. N-{{3-{3-[4-Acetyl-3-hydroxy-2-(3,3,3-trifluoropropyl)-phenoxy]-propoxy}-4-bromo-6-methyl-phenyl}}-oxamic acid of melting point 207°-209° is thus obtained.
