Procedure
109 ml (1.5 mol) of thionyl chloride are added dropwise at 0° C. with strong cooling to 240 ml of methanol. 60 g (0.5 mol) of L-threonine are then added and the mixture is stirred at room temperature for 2 days, a clear solution resulting. After concentration, 85 g of a colorless oil are obtained.
