Procedure

To a degassed solution of methyl 5-fluoro-6-(1,4-dioxaspiro[4.5]dec-7-en-8-yl)picolinate (1.0 equiv.) in MeOH (0.07M) was added 10% Pd/C (0.1 equiv.) and the reaction was stirred under a hydrogen balloon overnight. The solution was then filtered, rinsed with MeOH, and the filtrate was concentrated to afford methyl 5-fluoro-6-(1,4-dioxaspiro[4.5]decan-8-yl)picolinate in 91% yield. LC/MS=296.2 (M+H), Rt=0.83 min.
