Procedure

To 2-chloro-4-{3-chloro-4-[3,3,3-trifluoro-2-hydroxy-2-(2-isopropoxy-4-trifluoromethyl-quinolin-6-yl)-1-methyl-propyl]-phenoxy}-benzonitrile (53 mg) was added acetic acid (270 mg) and aqueous HCl (37%, 92 mg). The mixture was stirred at 60° C. for 24 h. The mixture was neutralized with aqueous NaOH solution and extracted with ethyl acetate. The organic phase was washed with water, dried (MgSO4), filtered and concentrated to dryness to give the title compound (46 mg) as an orange solid. MS (m/e, ISP neg. ion)=599.1 [M−H+].
