Reaction Steps

To benzyl alcohol (8.2 g) dissolved in benzene (30 mL) was added D-leucine (5.0 g) and p-toluenesulfonic acid monohydrate (8.0 g). The reaction was warmed to reflux with removal of water overnight. Once TLC indicated consumption of starting material, the reaction was cooled, and the resulting solid was filtered and washed with EtOAc to give the title compound as a white powder (14.26 g, 99%).
