Reaction Steps

1-[1-(1,2,3,4-Tetrahydronaphthalen-1-yl)piperidin-4-yl]-1,3-dihydro-2H-benzimidazol-2-one (476 mg) was dissolved in tetrahydrofuran (5 ml), 60% sodium hydride (66 mg) was added, and the suspension was stirred at 50° C. for 30 min. After cooling to room temperature, ethyl bromoacetate (0.167 ml) was added, and the mixture was stirred for 1 hr. 40% Methylamine-methanol solution (5 ml) was added, the mixture was stirred at room temperature for 1 hr, and the reaction mixture was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (chloroform/methanol) to give the title compound (567 mg) as a pale-yellow powder.
