A solution of ethyl (2,3-diamino-6-(2-methoxyethoxy)pyridin-4-yl)(4-((diethoxyphosphoryl)methyl)benzyl)carbamate (1 equiv.) in AcOH (0.15 M) was heated in a microwave at 100° C. for 5 min. At this point the volatiles were removed in vacuo. The resulting residue was purified by a COMBIFLASH™ system using a gradient of 0-10% MeOH/DCM to provide the title compound (63% over two steps) as a solid.
