Procedure

2 mL aqueous NaOH (1 M) was added at RT to a solution of 150 mg (0.270 mmol) ethyl 1-(2-{2-chloro-4-[2-(2-chloro-4-trifluoromethyl-phenoxy)-acetylamino]-phenoxy}-ethyl)-piperidine-4-carboxylate (Example 146) in 4 mL EtOH and the mixture was stirred for 16 h. The reaction mixture was neutralised with 2 mL aqueous HCl (1 M), evaporated down i. vac. and the crude product was purified by column chromatography (silica gel, dichloromethane/MeOH 4:1).
