Reaction Steps

EDC (80.2 mg, 0.42 mmol) was added to a stirred mixture of 5-chloro-2-[(3,3-difluoroazetidin-1-yl)methyl]benzylamine (68.8 mg, 0.28 mmol), N-BOC-L-proline (60.0 mg, 0.28 mmol) and HOAT (19.0 mg, 0.14 mmol) in DMF (2.5 mL). After 66 h the reaction 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 purified by chromatography on silica (eluting with EtOAc/CHCl3, 1:5) to give N-{5-chloro-2-[(3,3-difluoroazetidin-1-yl)methyl]benzyl}-1-(tert-butoxycarbonyl)-L-prolinamide (64.2 mg) as a glass: MS: 444.4 (M+1).
