The pyrazole compound (I) can be produced, for instance, by reacting a compound of the formula: ##STR3## wherein B is a halogen atom (e.g. chlorine, bromine), a mesyloxy group or a tosyloxy group with a compound of the formula: ##STR4## in the presence of an acid-eliminating ...
Then --OH in that group is replaced with fluoro by known methods, for example, directly by reaction with 2-chloro-1,1,2-trifluorotriethylamine or indirectly, for example, by transforming the hydroxy to tosyloxy or mesyloxy, and reacting the resulting compound with anhydrous potassium fluoride ...
