Reaktionsschritte

To a 3-l flask equipped with a stirrer, 200.0 g (0.93 mol) of 12-aminododecanoic acid, 600 g of methanol and 100 g (1.0 mol) of sulfuric acid were charged, followed by stirring at 60° C. for 5 hours. After the reaction mixture was allowed to cool down, it was diluted with methylene chloride, followed by neutralization with an aqueous solution of sodium carbonate. The solvent was distilled off under reduced pressure, followed by purification by chromatography on an alumina short column, whereby 201.7 g of the title compound (7-a) were obtained (yield: 95%).
