실험 절차

To a solution of N1-[1-(4-pyridyl)piperidin-4-yl-methoxycarbonyl]-1,2-benzenediamine (0.2 g, 0.6 mmol) and 4-difluoromethoxybenzoic acid (0.23 g, 1.2 mmol) in DMF (10 mL) was added 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.24 g, 1.2 mmol). After stirring overnight, the solvent was removed in vacuo and the residue was partitioned between ethyl acetate (300 mL) and 1 N NaOH (150 ml). The layers were separated and the organic phase was washed with brine, dried with MgSO4, filtered and concentrated in vacuo. The residue was purified by RPHPLC method A and the fractions containing pure product were combined and lypholized to give 123 mg (38%) of the title product as a white solid.
