Abstract
There is disclosed a process for preparation of L-carnitine from (S)-3-hydroxybutyrolactone. The process is a two-step preparation in which (S)-3-hydroxybutyrolactone is first converted to a hydroxy-activated form and subsequently transformed to L-carnitine by treatment of the hydroxy-activated (S)-3-hydroxybutyrolactone with trimethylamine in water.
