The excess trimethyl amine is distilled off. The pH of the solution is adjusted between 4 and 8, (3-carbalkoxy-2-oxopropyl)-trimethyl ammonium halide resulting. The (3-carbalkoxy-2-oxopropyl)-trimethyl ammonium is hydrogenated without isolating said halide from solution, a carnitine ester resulting.
