Versuchsvorschrift

To a mixture of the crude (S)-3-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-4-(isoquinolin-3-ylcarbamoyloxy)butanoic acid (1.47 mmol) and DMF (5 mL) were added DIEA (0.512 mL, 2.94 mmol) and HBTU (0.667 g, 1.76m mol). The resulting mixture was stirred at RT for 10 min and 2-aminomethyl pyrazine (0.192 g, 1.76 mmol) was added. The resulting mixture was stirred at RT for 30 min. The mixture was diluted with EtOAc (100 mL). The organic layer was washed by NaHCO3 solution and concentrated. The resulting residue was purified on silica gel column (DCM/MeOH) to give (S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-4-oxo-4-(pyrazin-2-ylmethylamino)butyl isoquinolin-3-ylcarbamate (0.65 g, 76.2%). LRMS (M+H+) m/z 580.1
