Benzazepinone (I) is alkylated by allyl bromide (II) in the presence of NaH to furnish (III). Ozonolysis of the N-allyl group of (III) in cold CH2Cl2 then produces aldehyde (IV). This is then reductively aminated with 5-fluoro-1-(piperidin-4-yl)-2,3-dihydro-1H-benzimidazol-2-one (V) employing NaBH(OAc)3 in 1,2-dichloroethane to yield the title compound.
