Versuchsvorschrift
Thus, in a five-step process: 5-fluoro-2-mercapto-benzoic acid ethyl ester may be reacted with 1-fluoro-2-nitrobenzene to form 5-fluoro-2-(2-nitro-phenylsulfanyl)-benzoic acid ethyl ester; the ethyl ester may be converted to 5-fluoro-2-(2-amino-phenylsulfanyl)-benzoic acid ethyl ester; the aminophenyl compound may be cyclized to form 2-fluoro-10H-dibenzo[b,f][1,4]thiazepin-11-one, that may be converted to 11-chloro-2-fluoro-dibenzo[b,f][1,4]thiazepine, and that may be then reacted with piperazine to form the title compound.
