white to off-white adhering crystalline powder | [Uses]
L-Alanine Ethyl Ester Hydrochloride is used in the synthesis of nucleoside phosphoramidates as antiviral agents for human immunodeficiency and hepatitis B viruses. Also used in synthesis of enantiomerically pure amino acid ester isocyanates. | [reaction suitability]
reaction type: solution phase peptide synthesis | [Synthesis]
L-alanine (3.56 g, 0.04 mol) was dissolved in ethanol (30 mL) at -5 °C and thionyl chloride (3.6 mL) was added slowly and dropwise, keeping stirring. Subsequently, the reaction mixture was warmed up to 78 °C and the reaction was refluxed in ethanol for 1.5 hours. Upon completion of the reaction, the solvent was removed by vacuum distillation to afford L-alanine ethyl ester hydrochloride (2a) in over 80% yield. The physical constants of the product 2a were in agreement with the data reported in literature [24]. | [References]
