The reduction of 1-[3-(dimethylamino)propyl]-1-(4-fluorophenyl)-3-oxo-1,3-dihydroisobenzofuran-5-carbonitrile (I) with LiAlH4 in THF/ethyl ether gives 5-(aminomethyl)-[3-(dimethylamino)propyl]-1-(4-fluorophenyl)-1,3-dihydroisobenzofuran (II), which is finally oxidized with Cu2Cl2 and oxygen in hot pyridine, or with K2S2O8 and NiSO4 in dichloromethane/water to yield the target compound.
