Procedure

To a solution of methyl ((3R,4R)-1-(2-chloro-5-cyano-3-((7-cyano-4-(cyclopropyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)-3-(phosphonooxy)piperidin-4 yl)carbamate (0.007 g, 0.009 mmol) in DCE (1 mL) was added anisole (0.006 mL, 0.055 mmol) followed by TFA (25% in DCE) (1.1 mL, 3.57 mmol) and at 35° C. for overnight. After completion of starting material (by LCMS), reaction mixture was concentrated and residue was taken in DCM (5 mL) concentrated under vacuum, the same thing was repeated one more time with 5 mL DCM. The resultant mixture was purified by reverse phase preparative HPLC and collected fractions were lyophilized to give methyl ((3R,4R)-1-(2-chloro-5-cyano-3-((7-cyano-4 (cyclopropylamino)imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)-3-(phosphonooxy)piperidin-4 yl)carbamate (0.003 g, 4.97 μmol, 51.28% yield) as white solid.
