The preparation of Example 13: 1-(3-Methyl-butyl)-piperidine-4-carboxylic acid (0.1 g, 0.50 mmol) was dissolved in DMF (5 mL) and treated with (4-Benzyloxy-phenyl)-(3-methyl-but-2-enyl)-piperidin-4-yl-amine (0.175 g, 0.50 mmol), diisopropylethylamine (0.26 mL, 1.5 mmol), and HBTU (0.19 g, 0.50 mmol). The reaction was stirred for 4 hours, then diluted with EtOAc (125 mL), washed with saturated sodium bicarbonate solution and brine, dried over Na2SO4, and concentrated. The residue was chromatographed on silica gel eluting with 8% MeOH/CH2Cl2 to give 47 mg (18%) of {4-[(4-Benzyloxy-phenyl)-(3-methyl-but-2-enyl)-amino]-piperidin-1-yl }-[1-(3-methyl-butyl)-piperidin-4-yl]-methanone.
