実験手順

To a solution of tert-butyl (3R, 5S)-3-(1-hydroxypropyl)-5-[{[1-(4-methoxybutyl)-1H-benzimidazol-2-yl]carbonyl}(2-methylpropyl)amino]piperidine-1-carboxylate (200 mg) in ethanol (1 ml) was added 12M hydrochloric acid (0.30 ml), and the mixture was stirred at room temperature for 1 hr. The reaction mixture was concentrated under reduced pressure, the residue was dissolved in ethanol, and ethanol was evaporated under reduced pressure. This operation was repeated twice to give the object product (140 mg).

後処理

  1. concentrationThe reaction mixture was concentrated under reduced pressure
  2. dissolutionthe residue was dissolved in ethanol
  3. customethanol was evaporated under reduced pressure
