    摘要: The present invention relates to a process for preparing compounds of formula (IV) where R is H or F, by reacting a compound of formula (II) where where R is H or F, and X is bromine, chlorine, mesylate, or tosylate, with a thiocyanate salt of formula (III) M+SCN−  (III) where M+ is hydrogen, an ammonium ion, a tetraalkylammonium ion, or an alkali metal or alkaline earth metal ion, optionally in the presence of a reaction auxiliary and optionally in the presence of a diluent.
