Participants

Reaction Steps

To a mixture of (S)-5-amino-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)pentyl 6-fluoroisoquinolin-3-ylcarbamate (0.40 g, 0.792 mmol), DIEA (0.276 mL, 1.58 mmol) and THF (2 mL), ethyl isocyanatoacetate (0.108 mL, 0.950 mmol) was added. The mixture was refluxed for 30 min, and concentrated. The remaining residue was purified on silica gel column (DCM/MeOH) to give (S)-ethyl 1-(2-chloro-3-fluorophenyl)-5-((6-fluoroisoquinolin-3-ylcarbamoyloxy)methyl)-4-methyl-3,10-dioxo-2,4,9,11-tetraazatridecan-13-oate (0.40 g, 80%). LRMS (M+H+) m/z 635.6.
