실험 절차
A mixture of 6-chloro-1-ethyl-1,5-dihydro-pyrrolo[3,2-c]pyridine-4-one (Intermediate G) (16 mg, 0.081 mmol) and 1-(2-fluorophenyl)piperazine (160 mg, 0.888 mmol) was heated at 140° C. in a sealed tube for 5 h. Flash chromatography (20/1 methylene chloride/methanol) afforded 1-ethyl-6-[4-(2-fluoro-phenyl)-piperazin-1-yl]-1,5-dihydro-pyrrolo[3,2-c]pyridin-4-one (18 mg, 65%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.3 (t, J=7.28 Hz, 3H) 3.1 (d, J=4.77 Hz, 4H) 3.2 (d, J=4.77 Hz, 4H) 4.0 (q, J=7.19 Hz, 2H) 5.8 (s, 1H) 6.3 (d, J=3.01 Hz, 1H) 6.9 (d, J=3.01 Hz, 1H) 7.1-7.2 (m, 3H) 10.6 (s, 1H). LC-MS calcd. for C19H22FN4O [(M+H)+] 341, obsd. 341.1.
