Procedure
Prepared similarly to that described in Example 210 using 2-(3-fluoroquinoxalin-5-yl)-6,7-dihydro-1H-pyrrolo[3,2-c]pyridin-4(5H)-one (Example 210i; 82 mg, 0.290 mmol) and 2,2-dimethylpyrrolidine (57.6 mg, 0.581 mmol; ChemBridge, San Diego, Calif.) and heating at 100° C. for 16 h. Purification by rpHPLC (Phenomenex Gemini C18, 10 μm, 150×30 mm; 10-100% ACN/water with 0.1% TFA) provided 2-(3-(diethylamino)quinoxalin-5-yl)-6,7-dihydro-1H-pyrrolo[3,2-c]pyridin-4(5H)-one (50% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.61 (s, 6H) 1.96-2.06 (m, 4H) 2.87 (t, J=6.94 Hz, 2H) 3.43 (td, J=6.85, 2.35 Hz, 2H) 3.78 (t, J=6.16 Hz, 2H) 6.95 (br. s., 1H) 7.07 (d, J=2.15 Hz, 1H) 7.36 (t, J=7.73 Hz, 1H) 7.66 (dd, J=8.02, 1.17 Hz, 1H) 7.89-7.94 (m, 1H) 8.62 (s, 1H) 11.99 (br. s., 1H).
