Procedure

A solution of 3-(2-fluoropyridin-3-yl)-1-(trifluoromethyl)cyclopent-2-enol (940 mg, 3.80 mmol) in tetrahydrofuran (35 mL) was treated with palladium, 10% wt. on activated carbon (202 mg, 0.190 mmol). The reaction mixture was purged through 3 vacuum-hydrogen cycles, and was stirred under hydrogen at 23° C. After 18 h, the reaction was filtered through celite and the filter cake was washed with tetrahydrofuran (50 mL). The combined filtrates were concentrated, affording the product as a yellow oil. MS (ESI, pos. ion) m/z: 250.0 (M+1).
