Two different ways to obtain talniflumate were developed: The first method is by reacting the previously salified niflumic acid (II) with 3-bromophthalide (I). The second way is by condensation of salified 2-halonicotinic acid (III) with 3-bromophthalide (I) to give the corresponding phthalidyl ester (IV), which is then treated with 3-trifluoromethylaniline (V).
