ethyl (2R)-2-amino-3-phenylpropanoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: D-Phenylalanine (250 mg, 1.52 mmol) was dissolved in 5 ml EtOH previously bubbled in HCl (gas). The solution was brought to 100° C. and allowed to reflux overnight. The solvent was evaporated off affording 280 mg crude product. Recrystallization from EtOH/EtOAc/pentane gave 239 mg (81% yield) of D-phenylalanine ethyl ester as white crystals. previously bubbled in HCl (gas) was brought to 100° C. to reflux overnight The solvent was evaporated off affording 280 mg crude product Recrystallization from EtOH/EtOAc/pentane
