Reaction Steps

Ethyl N-[2-amino-6-(methyloxy)-3-pyridinyl]glycinate (40.6 g, 135 mmol) was dissolved in tetrahydrofuran (THF) (1 L) at room temperature under argon and treated with potassium tert-butoxide (15.17 g, 135 mmol). After 2 h at room temperature saturated NH4Cl (500 ml) was added and the THF evaporated. Water (500 ml) was added followed by 20% MeOH/DCM (1 L); the insoluble material was filtered off, washed with diethyl ether and dried in the vacuum oven at 40° C. overnight to afford the desired product as a yellow solid (15.3 g): LCMS and NMR consistent with product (9% of oxidized material present by NMR).
