실험 절차

To a solution of methyl 4′-[[2-[(tert-butoxycarbonyl)-[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]amino]-ethyl]amino]-3-(cyclohexyloxy)-4-biphenylcarboxylate (125 mg) in methanol (1.750 ml) and tetrahydrofuran (0.900 ml) was added 1N aqueous sodium hydroxide solution (1.05 ml) and the mixture was stirred at room temperature for 1 day. To the reaction mixture was added 1N aqueous sodium hydroxide solution (0.900 ml) and the mixture was stirred at room temperature for 3 days. The reaction mixture was concentrated under reduced pressure and to the residue were added ethyl acetate (40 ml) and water (20 ml). The pH value was adjusted to 5.70 by addition of 0.1N hydrochloric acid and the separated organic layer was washed with water and brine and dried over magnesium sulfate. Filtration followed by evaporation gave 4′-[[2-[(tert-butoxycarbonyl)[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]amino]ethyl]amino]-3-(cyclohexyloxy)-4-biphenylcarboxylic acid (123 mg) as a yellow foam.
