To a solution of 4-benzyloxy-phenyl-acetic acid (39 mg, 0.16 mmol) and HATU (61 mg, 0.16 mmol) in DMF (3 mL) is added N-methylmorpholine (64 mg, 0.64 mmol) followed by a solution of ((S)-5-amino-1-{[(3,5-diamino-6-chloro-pyrazine-2-carbonyl)-amino]-methyl}-pentyl)-carbamic acid tert-butyl ester (Intermediate C) (64 mg, 0.16 mmol) in DMF (2 mL). The resulting mixture is stirred at RT for 17 h. The solvent is removed in vacuo to afford the title compound which is used in the next step without further purification. [M+H]+ 626.
