Reaction Steps

To ethyl 4-[5-(3-methyl-5-{[4-(trifluoromethyl)pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]-cyclohex-3-ene-1-carboxylate (0.15 g, 0.31 mmol) was added ethanol (2 mL) and argon was bubbled through the solution for 5 minutes. The flask was then purged/filled with argon three times. 10% Palladium on carbon (0.33 mg) was added to the flask and the flask was purged/filled with argon three times. A hydrogen balloon was added to the top of the flask and the reaction was purged/filled with argon three times. The reaction was stirred for 72 hours. Upon completion, the reaction was filtered carefully through celite and the celite pad was washed with methanol (70 mL). The filtrate was concentrated under reduced pressure and the solid was purified by silica gel chromatography to yield ethyl 4-[5-(3-methyl-5-{[4-(trifluoromethyl)-pyrimidin-2-yl]amino}phenyl)-1,3-thiazol-2-yl]cyclohexanecarboxylate (0.73 g, 49% yield).
