Reaction Steps

Diethyl 2-(3-pyridylmethyl)-2-acetamidomalonate was dissolved in 6N HCl (30 mL) and heated to reflux for 19 hours whereupon it was cooled to room temperature and the HCl solution was removed by evaporation in vacuo. The intermediate amino acid dihydrochloride salt was taken up into MEOH (30 mL) saturated with HCl gas and stirred for 3.5 hours. The MeOH/HCl was removed by evaporation in vacua to give 3-(3-pyridyl)alanine methyl ester dihydrochloride (2.235 g, 100%).
