The condensation of 2-iodophenylacetic (I) with 4-fluorophenol (II) by means of K2CO3 in nitrobenzene al 160 C gives 2-(4-fluoophenoxy)phenylacetic acid (III), which by treatment with refluxing SOCl2 is converted to the corresponding acid chloride (IV). The cyclization of (IV) by means of AlCl3 in refluxing dichloroethane affords 2-fluoro-10,11-dihydro-11-oxodibenzo[b,f]oxepin (V), which is treated with 2-(dimethylamino)ethylthiol (VI) and boron trifluoride ethereate in acetic acid yielding 2-fluoro-11-[2-(dimethylamino)ethythio]dibenzo[b,f]oxepin (VII). The reaction of (VII) with phenyl chloro-formate (VIII) by means of K2CO3 in methylene chloride affords 2-fluoro-11-[2-(N-methyl-N-phenyloxycarbonylamino)ethythio]dibenzo[b,f]oxepin (IX), which is finally hydrolyzed with KOH-ethylene glycol al 155 C.
