実験手順
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; 93 mg, 0.329 mmol) and 2,2-dimethylazetidine (84 mg, 0.988 mmol; FCH Group, Chernigov, Ukraine), heating at 100° C. for 4 h. Purification by silica gel (100% DCM to 4% MeOH/DCM) provided 2-(3-(2,2-dimethylazetidin-1-yl)quinoxalin-5-yl)-6,7-dihydro-1H-pyrrolo[3,2-c]pyridin-4(5H)-one (59% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.66 (s, 6H) 2.27 (t, J=7.53 Hz, 2H) 2.87 (t, J=6.85 Hz, 2H) 3.42 (td, J=6.75, 2.15 Hz, 2H) 4.14 (br. s., 2H) 6.95 (br. s., 1H) 7.12 (d, J=2.15 Hz, 1H) 7.36 (t, J=7.73 Hz, 1H) 7.64 (d, J=8.02 Hz, 1H) 7.95 (d, J=7.43 Hz, 1H) 8.35 (br. s., 1H) 12.09 (br. s., 1H).
