The title compound is prepared by two related methods. N-Benzyl-4-piperidone (I) is condensed with KCN and MeNH2.HCl to produce amino nitrile (II). Partial hydrolysis of nitrile (II) with H2SO4 furnishes amide (III). Condensation of the amino amide (III) with triethyl orthoformate gives rise to the spiro imidazolinone (IV). Catalytic hydrogenation of the imidazoline double bond of (IV) and simultaneous N-benzyl group hydrogenolysis gives rise to 1-methyl-1,3,8-triazaspiro[4,5]decan-4-one (V). This is finally alkylated with 4'-fluoro-4-chlorobutyrophenone (VI) to yield the desired compound (1,2).
