(4-Benzyloxycarbonylamino-phenyl)-(3-methyl-butyl)-piperidin-4yl-amine (0.22 g, 5.64 mmol) was dissolved in DMF (30 mL), treated with Hunig's base (3.93 mL, 22.6 mmol), (S)-2-[(Azepane-1-carbonyl)-amino]-4-methyl-pentanoic acid (1.36 g, 5.64 mmol), and HBTU (2.04 g, 5.64 mmol), and stirred for 1 hour. The reaction was diluted with EtOAc (200 mL), washed with saturated bicarbonate solution and brine, dried over Na2SO4, and concentrated. The residue was chromatographed on silica gel eluting with 5% MeOH/CH2Cl2 to give 2.76 g (77%) of the desired product.
