Procedure

To a solution of 2-fluoro-3-(1,4-dioxaspiro[4.5]dec-7-en-8-yl)pyridine (7.99 g, 34.0 mmol) in THF (40 mL) under argon atmosphere was added palladium on carbon (10% activated, 0.80 g). The mixture was placed under 1 atmosphere of hydrogen and stirred for 5 h at 40° C. After placing the mixture back under argon atmosphere, the mixture was filtered through celite and the filtrate was concentrated in vacuo to give 2-fluoro-3-(1,4-dioxaspiro[4.5]decan-8-yl)pyridine MS (ESI, pos. ion) m/z: 238.1.
