Procedure

Dissolve 1 -benzyloxycarbonyl-5-hydroxy-(S)-pipecolic acid (prepared from 5-hydroxy-(S)-pipecolic acid in 2N sodium hydroxide solution treated with benzylchlorformate in diethyl ether) in acetone and treat with Jones reagent to obtain 1-benzyloxycarbonyl-5-keto-(S)-pipecolic acid. Then esterify in methanol to give the respective methyl ester.
