Reaction Steps

4-(4-Methylpiperidin-4-yl)-3,4-dihydropyrrolo[4,3,2-de][2,6]naphthyridin-5(1H)-one (21 mg, 0.078 mmol) and triethylamine (0.032 mL, 0.233 mmol) were dissolved in EtOH (4 mL) and cooled to 0° C. and allowed to stir for 10 min. Then 2,5-dioxopyrrolidin-1-yl 2-cyanoacetate (17 mg, 0.093 mmol) dissolved in EtOH (1 mL) was added dropwise and the mixture was allowed to stir for 30 min at 0° C. The solution was concentrated in vacuo and purified via preparative HPLC 10% to 40% B in A and gave 13 mg of the title compound as its TFA salt. 1H NMR (400 MHz, CD3OD) δ 7.61 (m, 1H), 7.43 (m, 1H), 5.08 (s, 2H), 3.90 (m, 2H), 3.72 (m, 1H), 3.61-3.62 (m, 1H), 3.51-3.52 (m, 2H), 2.65-2.69 (m, 1H), 2.51-2.57 (m, 1H), 2.22-2.26 (m, 1H), 2.10-2.12 (m, 1H), 1.66 (s, 3H). [M+H] found 338.
