Procedure
The 5-fluoro-2-benzo[b]thiophenecarboxylic acid prepared above in A was converted to ethyl 5-fluoro-2-benzo[b]thiophenecarbodithioate (mp 91-92° C.) using the procedures described above in Examples 2(B)-2(D). NMR confirmed the structure as that of ethyl 5-fluoro-2-benzo[b]thiophenecarbodithioate.
