Procedure

2.1 g (0.007 mole) of 4-[bis(4-fluorophenyl)hydroxymethyl]piperidine, 1.8 g (0.007 mole) of 1-(1-bromo-3-propyl)-1,3-dihydro-2(2H)-benzimidazolone, 0.85 g (0.008 mole) of Na2CO3 and a few crystals of NaI are heated for 5 h at reflux temperature in 60 ml of methyl isobutyl ketone. The solvent is evaporated off, the residue is taken up with a mixture of water and CH2Cl2, and the organic phase is dried and evaporated down. A solid residue is obtained which is chromatographed on a column of silica (eluent: CH2Cl2/MeOH 97/3, 96/4 and then 94/6). The pure fractions are evaporated down, the evaporation residue is taken up with ether and a white product is filtered off and crystallized from 90 ml of ethyl acetate. M.p.=141°-143° C.
