2-Chloro-N-cyclopropyl-4-[3-oxo-3-({2,2,2-trifluoro-1-[3-(trifluoromethyl)phenyl]ethyl}amino)-prop-1-yn-1-yl]benzamide (110 mg, 0.20 mmol), quinoline (10 mg, 0.07 mmol) and palladium on calcium carbonate (5% Pd; 10 mg) were suspended in methanol and stirred for 4 days, in the course of which palladium on calcium carbonate (3×10 mg) was added again every 24 h. Then the reaction mixture was filtered through kieselguhr, and the filtrate concentrated to dryness under reduced pressure. The residue was purified by means of silica gel chromatography with the eluent cyclohexane/ethyl acetate (EA) (0% EA to 50% EA).
