Versuchsvorschrift

To a solution of about 4.50 g of N-acetyl-L-serine, methyl ester in about 100 ml of dry methylene chloride was added about 2.93 ml of distilled tetrahydro-2H-pyran and about 0.34 ml of borontrifluoroetherate. The mixture was stirred under argon for about 7 hours, then washed with saturated sodium bicarbonate and brine, dried and the solvent removed under reduced pressure, giving about 6 g of the desired title compound.
