Participants

Reaction Steps

A mixture of 5-(3,4-difluorophenyl)-2,3-dihydro-4-methoxycarbonyl-1-(3-bromoprop-1-yl)aminocarbonyl-2(1H)-imidazolone (386 mg, 0.92 mmol), 4-(2-methoxyphenyl)piperazine (353 mg, 1.84 mmol), potassium carbonate (382 mg, 2.76 mmol) and sodium iodide (138 mg, 0.92 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 eluting with EtOAc/MeOH (9:1) to give the desired product (2% yield). Hydrochloride salt: yellow solid; m.p. 122-124° C.
