Benzyl Alcohol → HCID 86735353, compound

Participants

Reaction Steps

To a solution of 55.8 g of N-(2-methoxyethyl)glycine tert-butyl ester in 200 ml of benzene was added 63.8 g of benzyl alcohol and 72.9 of p-toluenesulfonic acid monohydrate. The mixture was heated at reflux for 10 hours with the continuous removal of water through a Dean-Stark water trap. At the end of this period, the solution was concentrated in vacuo, and to the residue was added 300 ml of dry ethyl ether. After 2 hours at room temperature, the formed precipitate was filtered, washed with dry ethyl ether and then recrystallized from ethyl acetate to yield 99.2 g (85 percent) of N-(2-methoxyethyl)glycine benzyl ester p-toluenesulfonate, M.P. 95°-6° C.
