Procedure

To a solution of 2-tert-butoxycarbonylamino-2-ethyl-4-(4-(4-phenylbutyloxy)phenyl)butyl acetate (3.4 g) in methanol (50 ml) was added a solution of lithium hydroxide monohydrate (0.33 g) in water (10 ml) and the mixture was stirred at room temperature for 20 minutes. The reaction mixture was poured into water and extracted with ethyl acetate. The ethyl acetate layer was washed with a saturated brine and dried over anhydrous sodium sulfate. The solvent was distilled away under reduced pressure to give the subject compound (3.6 g).
