Reaction Steps

1-(2-Ethoxyphenyl)-3-[2-(1-{[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazol-4-yl]prop-2-yn-1-one (130 mg) was dissolved in methanol and hydrogenated at 40° C. and an H2 pressure of 10 bar and in the presence of Pd/C (10%). This gave, after filtration and removal of the solvent under reduced pressure, 1-(2-ethoxyphenyl)-3-[2-(1-{[5-methyl-3-(trifluoromethyl)-1H-pyrazol-1-yl]acetyl}piperidin-4-yl)-1,3-thiazol-4-yl]propan-1-one (40 mg).
