(R)-2-(6-Chloro-3-oxopyrrolo[4,3,2-de][2,6]naphthyridin-4(1H,3H,5H)-yl)-3-methylbutanoic acid (10 mg, 0.032 mmol)), HATU (15 mg, 0.039 mmol), (2S,4S)-4-fluoropyrrolidine-2-carbonitrile (4 mg, 0.032 mmol), and N-methylmorpholine (90 μL, 0.097 mmol) were combined in THF (0.5 mL). The reaction mixture was stirred under nitrogen at 40° C. for 10 min and then at room temperature for 30 min. The solution was concentrated and purified by preparative HPLC (10-50% AcCN/H2O with 0.035% TFA) to afford the title compound as a white solid (2 mg, 12%). 1H NMR (500 MHz, CD3OD) δ 0.94 (d, J=6.3 Hz, 3H), 1.05 (d, J=6.3 Hz, 3H), 1.03-1.15 (m, 1H), 2.56-2.65 (m, 3H), 23.89-3.91 (m, 1H), 4.25-4.30 (m, 1H), 4.83-4.87 (m, 1H), 5.09-5.13 (m, 1H), 5.39-5.41 (m, 1H), 5.47-5.66 (m, 1H), 7.87 (s, 1H), 8.27 (s, 1H). [M+H] calc'd for C19H19ClFN5O2, 404; found, 404.
