Reaction Steps

To a solution of 2-amino-5-(4-(2-(3-(diethoxyphosphoryl)-3,3-difluoropropoxy)ethoxy)-2-methoxybenzyl)-6-methylpyrimidin-4-yl 2,4,6-trimethylbenzenesulfonate (1 equiv.) in EtOAc (0.20 M) was added TFA (1.1 equiv.) and amylamine (3.3 equiv.). The reaction mixture was then heated to 100° C. for 18 h. At this point the reaction mixture was allowed to cool to room temperature and 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 (76%) as a solid.
