実験手順
EDC (1.51 g, 7.87 mmol) was added to a stirred mixture of 5-chloro-2-[(3-hydroxyazetidin-1-yl)methyl]benzylamine (1.19 g, 5.25 mmol), N-Boc-L-proline (1.13 g, 5.25 mmol) and HOAT (0.36 g, 2.62 mmol) in DMF (9 mL). After 16 h the mixture was concentrated and the residue was partitioned between EtOAc and 10% NaHCO3. The organic layer was washed with water and brine, dried (Na2SO4)and evaporated. The residue was partitioned between EtOAc and 1M citric acid. The aqueous layer was made neutral with NaHCO3 and was extracted into CH2Cl2. The organic layer was evaporated and the residue was purified by chromatography on silica (ammonia saturated CHCl3/MeOH, 95:5) to give N-{5-chloro-2-[(3-hydroxyazetidin-1-yl)methyl]benzyl}-1-(tert-butoxycarbonyl)-L-prolinamide (210 mg) as a glass: MS: 424.5 (M+1).
