3-Cyano-5-(trifluoromethoxy)benzoic acid → 3-Cyano-N-{4-methyl-3-[6-(pyridin-3-yl)-1H-imidazo[1,2-b]pyrazol-1-yl]phenyl}-5-(trifluoromethoxy)benzamide

Reaction Steps

Analogously to the procedure for Example 33, 50 mg (0.17 mmol) of the compound of Example 6A and 40 mg (0.18 mmol) of the compound of Example 41A were reacted with one another. After purification of the crude product by preparative HPLC, the product-containing fractions were concentrated to a small residual volume and made alkaline with a little saturated aqueous sodium bicarbonate solution. The precipitate formed was filtered off, washed with water and dried. This gave 56 mg (65% of theory) of the title compound.
