Reaction Steps

To a solution of (S)-tert-butyl 4-(2-(tert-butoxycarbonyl(methyl)amino)-3-(6-fluoroisoquinolin-3-ylcarbamoyloxy)propyl)-1H-imidazole-1-carboxylate (280 mg, 0.51 mmol) in THF (10 mL) was added HCl (4 N in 1,4-dioxane, 2.55 mL, 10.2 mmol). The reaction mixture was stirred at RT for 1 h and concentrated to dryness. The residue was suspended in THF (20 mL). To the suspension were added DIEA (0.27 mL, 1.53 mmol) and 4-nitrophenyl 2-chloro-3-fluorobenzylcarbamate (166 mg, 0.51 mmol). The reaction mixture was stirred at RT for 2 h and concentrated to dryness. The residue was purified on RP-HPLC using a mixture of acetonitrile and water to give (S)-2-(3-(2-chloro-3-fluorobenzyl)-1-methylureido)-3-(1H-imidazol-4-yl)propyl 6-fluoroisoquinolin-3-ylcarbamate (35 mg, 13%). LRMS (M+H+) m/z 529.5.
