Procedure

To a solution of (S)-tert-butyl 3-((7-fluoro-3-(hydrazinyl(imino)methyl)isoquinolin-1-yl)amino)pyrrolidine-1-carboxylate (0.35 g, 1 mmol) in dioxane (10 mL) was added CDI (0.36 g, 2 mmol) under a nitrogen atmosphere. The mixture was heated to reflux for 2 hours and was subsequently concentrated in vacuo. The crude product was purified by preparative HPLC to give the title compound (120 mg, 34%). ESI-MS m/z [M+H]+ 415.2.
