Reaction Steps
1-tert-Butyl 3-methyl (3R,5S)-5-{{{4-fluoro-1-(4-methoxybutyl)-1H-benzimidazol-2-yl}carbonyl}(2-methylpropyl)amino}piperidine-1,3-dicarboxylate (195 mg) was dissolved in tetrahydrofuran-methanol (1:2, 15 ml), 2M aqueous sodium hydroxide solution (1 ml) was added, and the mixture was stirred at 45° C. for 4 hr. The reaction mixture was concentrated under reduced pressure, neutralized with saturated aqueous ammonium chloride solution and extracted with ethyl acetate. The extract was dried over anhydrous magnesium sulfate, concentration under reduced pressure to give the object product (180 mg).
