To a solution of 1-{N-[(methyloxy)carbonyl]-L-valyl}-8-oxa-1-azaspiro[4.5]decane-2-carboxylic acid (168) (52 mg, 1.5 mmol) and methyl {(1S)-1-[((2S)-2-{4-[4′-(aminoacetyl)-4-biphenylyl]-1H-imidazol-2-yl}-pyrrolidinyl)carbonyl]-2-methylpropyl}carbamate dihydrochloride (1) (88 mg, 0.15 mmol) and HATU (58 mg, 0.15 mmol) in anhydrous dichloromethane (1.2 mL) was added Hunig's base (0.12 mL, 0.68 mmol) and the reaction stirred at room temperature for 1 h. The reaction was concentrated in vacuo and purified by HPLC eluting with 10-90% water/acetonitrile/0.2% NH4OH to afford the title compound as an off-white solid (73 mg, 58% yield).
