Reaction Steps

To a stirred solution of 1-[5-chloro-2-(4-chloro-1,2,5-thiadiazol-3-yl)phenyl]methanamine (28.1 mg, 0.11 mmol), 1-{(2R)-2-[(tert-butoxycarbonyl)amino]-2-cyclohexylethanoyl}-L-proline (prepared by standard peptide coupling protocols, 38.3 mg, 0.11 mmol) and HOAt (19.1 mg, 0.14 mmol) in DMF (1.0 mL) was added EDC (26.9 g, 0.14 mmol). After 16 h the mixture was partitioned between EtOAc and water. The organic phase was washed with brine dried (Na2SO4) and reduced in vacuo. The residue was purified by HPLC (C18 eluting with an acetonitrile/water/0.1% TFA gradient). 1-{(2R)-2-[(tert-Butoxycarbonyl)amino]-2-cyclohexylethanoyl}-N-[5-chloro-2-(4-chloro-1,2,5-thiadiazol-3-yl)benzyl]-L-prolinamide was obtained as a solid. LCMS m/z=596.5.
