Procedure
To a stirring solution of (3-{3-[(2-chloro-3-trifluoromethyl-benzyl)-diphenylethyl-amino]-propoxy}-phenylamino)-acetic acid methyl ester in THF (6 ml) and water (2 ml) was added lithium hydroxide monohydrate (20 mg, 0.47 mmol) and the mixture was stirred at room temperature for 6 hours. The reaction mixture was acidified with 1 M aqueous HCl (0.5 mL). The aqueous mixture was concentrated in vacuo and the crude material was dissolved in EtOAc. The ethyl acetate solution was washed with brine (1×), dried over sodium sulfate, and filtered. The organic layer was concentrated, and the crude amine was treated with 1 M HCl (Et2O). The resulting precipitate was dried under vacuum to afford the title compound as a solid. MS(ES) m/e 597.4 (M+).
