실험 절차

A mixture of 1-trichloroacetyl-5-(3,4-difluorophenyl)-2,3-dihydro-4-methoxycarbonyl-2(1H)-imidazolone (583 mg, 1.46 mmol), 1-(3-aminopropyl)-4-methoxycarbonyl-4-phenylpiperidine (808 mg, 2.92 mmol) and potassium carbonate (809 mg, 5.85 mmol) in dioxane (15 mL) was heated at reflux for 24 hours and then concentrated. The residue was partitioned between EtOAc and water. The organic layer was dried over Na2SO4, filtered and concentrated to give the crude product which was flash chromatographed over silica gel to give the product (15 mg, 2% yield). Hydrochloride salt: light brown solid; m.p. 134-136° C.
