Procedure

(R)-2-(6-Fluoro-3-oxopyrrolo[4,3,2-de][2,6]naphthyridin-4(1H,3H,5H)-yl)-3-methylbutanoic acid (15 mg, 0.051 mmol), HOBt hydrate (9.46 mg, 0.062 mmol), and EDC hydrochloride (14.81 mg, 0.077 mmol) were combined in DMF (2 mL). 3,3-Difluoroazetidine hydrochloride (10.0 mg, 0.077 mmol) and 4-methylmorpholine (0.023 mL, 0.206 mmol) were added, and the reaction mixture was stirred at room temperature for 2 h. Following reaction, the product was purified by preparative HPLC (10-60% AcCN/H2O with 0.035% TFA), concentrated in vacuo, and lyophilized to afford the title compound as a white solid (10 mg, 53%). 1H NMR (500 MHz, DMSO-d6) δ 0.80 (d, J=6.0 Hz, 3H), 0.96 (d, J=6.0 Hz, 3H), 2.30-2.41 (m, 1H), 4.26-4.36 (m, 2H), 4.41-4.51 (m, 1H), 4.70-4.79 (m, 1H), 5.00 (AB q, J=104.5, 22.0 Hz, 2H), 5.07 (d, J=23.0 Hz, 1H), 7.99 (d, J=2.5 Hz, 1H), 8.24 (d, J=2.5 Hz, 1H), 12.40 (s, 1H). [M+H] calc'd for C17H17F3N4O2, 367; found, 367.
