Versuchsvorschrift

Methyl 3-[2-[(1R)-1-[(2R)-2-hydroxy-3-[[2-methyl-1-(naphthalen-2-yl)propan-2-yl]amino]propoxy]ethyl]phenyl]propionate (539 mg) obtained in Step 4 was dissolved in methanol (20 ml) and tetrahydrofuran (20 ml), 4N aqueous sodium hydroxide (2.5 ml) was added and the mixture was stirred at 50° C. for 8 hr. The reaction mixture was concentrated under reduced pressure. The obtained residue was diluted with water, neutralized with 10% aqueous citric acid, and the mixture was extracted with ethyl acetate. The organic layer was washed successively with water and brine, dried over anhydrous sodium sulfate, and concentrated under reduced pressure to give the title compound (332 mg).
