Procedure

To a solution of (S)-3-amino-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)propyl isoquinolin-3-ylcarbamate (200 mg, 0.44 mmol) in THF (2.0 mL) were added 2,2-difluoroethyl trifluoromethanesulfonate (94 mg, 0.44 mmol) and DIEA (0.15 mL, 0.88 mmol) at RT The reaction mixture was stirred at RT for 30 min. The solvent was removed. The resulting residue was dissolved in MeOH and mixture was purified on RP-HPLC using a mixture of acetonitrile and water to give (S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-3-(2,2-difluoroethylamino)propyl isoquinolin-3-ylcarbamate (130 mg, 56% for two steps). LRMS (M+H+) m/z 524.2.
