Procedure

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide (0.10 g, 0.53 mmol) was added to a solution of furan-2-carboxylic acid (0.059 g, 0.53 mmol), (S)-2-Amino-3-cyclohexyl-N-((3S,4S,7R)-3-hydroxy-7-methyl-1-propyl-azepan-4-yl)-propionamide (0.15 g, 0.36 mmol), 4-methylmorpholine (0.14 g, 0.16 ml, 1.44 mmol), hydroxybenztriazole (0.071 g, 0.53 mmol) in DMF (2.0 ml) and was stirred at RT overnight. The reaction mixture was then warmed to RT and was stirred overnight. The reaction mixture was diluted with EtOAc (30 ml), washed with H2O, brine, dried with magnesium sulfate, filtered, concentrated in vacuo by rotary evaporation, and chromatographed (silica gel, 2.5% MeOH/CH2Cl2) to yield the title compound (0.12 g, 76%): Electrospray mass spec: M+H+=434.2.
