Reaction Steps

To a solution of methyl 6-(4-(tert-butyldimethylsilyloxy)cyclohexyl)-5-fluoropicolinate (1.0 equiv.) in THF/MeOH (2:1, 0.09 M) was added LiOH (1.5 equiv.). The reaction mixture was stirred overnight at room temperature, then 1N HCl and ethyl acetate were added, the organic phase was washed with brine, dried over magnesium sulfate, filtered and concentrated to give 6-(4-(tert-butyldimethylsilyloxy)cyclohexyl)-5-fluoropicolinic acid as a mixture of isomers (3:1) in 82% yield. LC/MS=354.2 (M+H), Rt=1.38 and 1.41 min.
