Procedure

To a solution of (S)-4-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-5-(6-fluoroisoquinolin-3-ylcarbamoyloxy)pentanoic acid (83 mg, 0.160 mmol, 1.0 equiv) in DMF (1 mL) were added HBTU (72 mg, 0.191 mmol, 1.2 equiv.), tert-butyl-1-piperazine carboxylate (59 mg, 0.320 mmol, 2.0 equiv.) and DIEA (83 μL, 0.480 mmol, 3.0 equiv.). The reaction mixture was stirred 1 h at RT and purified on RP-HPLC using a mixture of acetonitrile and H2O to give (S)-tert-butyl 4-(4-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-5-(6-fluoroisoquinolin-3-ylcarbamoyloxy)pentanoyl)piperazine-1-carboxylate (61 mg, 55%). LRMS (M+H+) m/z 689.3.
