Procedure

1-(2,2-Diphenylethyl)-3-carboxy piperidine(472 mg, 1,52 mmol),3-(4-cyanobenzyl) histamine (456 mg, 1.52 mmol) (EXAMPLE 1, Step E) HOBT (216 mg, 1.60 mmol), EDC (307 mg, 1.60 mmol), and Et3N (637 uL, 4.57 mmol) were dissolved in DMF (10 mL) and was stirred overnight at ambient temperature. The solution was concentrated under reduced pressure and chromatographed (silica gel, 0.5-2% MeOH/CH2Cl2 with NH4OH) to give the title compound 1H NMR (CDCl3) δ 7.96 (br s, 1H), 7.60 d, 2H, J=8 Hz), 7.46 (s, 1H), 7.09-7.37 (m, 12H), 6,74 (s, 1H), 5.20 (s, 2H), 4.26 (t, 1H, J=8 Hz), 3.05-3.17 (m, 2H), 2.93-3.04 (m,1H), 2.78-2.91 (m,2H), 2.49-2,61 (m 1H), 22.40-2.47 (m, 1H), 2.15-2.30 (m, 2H), 1.95-2.14 (m, 2H), 1.86 (d, 1H, J=12 Hz), 1.29-1.55 (m, 3H).
