2-Methoxyethanol → Ethyl (2-amino-6-(2-methoxyethoxy)-3-nitropyridin-4-yl)(4-((diethoxyphosphoryl)methyl)benzyl)carbamate

Participants

Reaction Steps

To a solution of ethyl (2-amino-6-bromo-3-nitropyridin-4-yl)(4-((diethoxyphosphoryl)methyl)benzyl)carbamate (1 equiv.) in THF (0.30 M) was added sodium hydride (5 equiv.) in a solution of 2-methoxyethanol (0.50 M). The reaction mixture was allowed to stir at room temperature for 2 h. At this point the volatiles were removed in vacuo. The resulting residue was purified by a COMBIFLASH™ system using a gradient of 0-5% MeOH/DCM to provide the title compound (68%) as a solid.
