(4-Benzyloxycarbonylamino-phenyl)-(3-methyl-but-2-enyl)-piperidin-4-yl-amine (0.35 g, 0.88 mmol) was dissolved in; DMF (8 mL), treated with Hunig's base (0.47 mL, 2.64 mmol), (S)-2-[(azepane-1-carbonyl)-amino]-4-methyl-pentanoic acid (0.21 g, 0.88 mmol), and HBTU (0.34 g, 0.88 mmol). The reaction was stirred 2 hours, then diluted with EtOAc (100 mL), washed with saturated sodium bicarbonate solution and brine, dried over Na2SO4, and concentrated. The residue was chromatographed on silica gel eluting with 5% MeOH/CH2Cl2 to give 0.49 g (93%) of the desired product.
