To a suspension of crude methanesulfonic acid 4-[(1,3-dioxo-2,3-dihydro-1H-isoquinolin-4-ylidenemethyl)-amino]-benzyl ester (72 mg, 0.23 mmol) in N,N-dimethylformamide (2 mL) is added pyrrolidine (21 μL, 0.25 mmol). The reaction mixture is shaken at ambient temperature for 16 hours. The reaction mixture is diluted to 2 mL with N,N-dimethylformamide and purified by C18 reverse phase HPLC. The pure fractions were combined and concentrated to yield the title compound (3.0 mg).
