Reaction Steps

Lithium borohydride (0.83 g) was added to a solution of ethyl 2-ethyl-2-methoxycarbonylamino-4-(4-(4-phenylbutyloxy)phenyl)butanoate (5.6 g) in tetrahydrofuran (130 ml) and the mixture was refluxed under heating for 4 hours and allowed to stand at room temperature overnight. 2M Hydrochloric acid (11 ml) and water (400 ml) were added to the reaction mixture under ice-cooling and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with a saturated brine, dried over anhydrous sodium sulfate and the solvent was distilled away under reduced pressure. The residue obtained was purified by silica gel column chromatography (eluent; ethyl acetate:n-hexane=1:1) to give the subject compound (3.0 g).
