Procedure
To a stirred solution of 24.2 parts of 1-(4-fluorophenyl)-1,3-dihydroisobenzofuran-1-propanol in 8 parts of pyridine and 90 parts of trichloromethane were added dropwise 12.1 parts of thionyl chloride. Upon completion, the whole was heated slowly to 50° C. and stirring at this temperature was continued for 3 hours. The reaction mixture was poured onto ice-water. The organic phase was separated, washed with a sodium hydrogen carbonate solution (10%), dried and evaporated, yielding 20 parts of 1-(3-chloropropyl)-1-(4-fluorophenyl)-1,3-dihydroisobenzofuran as a residue (intermediate 12).
