실험 절차

To a mixture of the piperidine hydrochloride from example 1 step G (102 mg, 0.447 mmol), [1-(4-cyanobenzyl)-1H-imidazol-5-yl]acetic acid (from step D) (127 mg, 0.447 mmol), HOOBT (73 mg, 0.447 mmol) and triethylamine (0.187 ml, 1.34 mmol) in DMF (3 ml)was added EDC (86 mg, 0.447 mmol) and the reaction stirred at room temperature for 18 hrs. The reaction was diluted with EtOAc and washed with saturated NaHCO3 solution. The organic extracts were dried (Na2SO4) and the solvent evaporated in vacuo. The residue was purified by preparative HPLC (C-18, gradient elution, 95:5 to 5:95 water: acetonitrile containing 0.1% trifluoroacetic acid). Lyophilization afforded the title compound as a white powder.
