الإجراء التجريبي

(S)-4-(4-((6-oxo-6,6a,7,8,9,10-hexahydro-5H-dipyrido[1,2-a:3′,2′-e]pyrazin-3-yl)methyl)piperazin-1-yl)benzoic acid (50 mg, 0.119 mmol) was taken up in DMF (0.5 mL). To the mixture was added N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (34.1 mg, 0.178 mmol), 1H-benzo[d][1,2,3]triazol-1-ol hydrate (27.2 mg, 0.178 mmol), 4-methylmorpholine (0.065 mL, 0.593 mmol) and cyclopropanamine (6.77 mg, 0.119 mmol). The reaction was stirred at room temperature overnight. To the stirred solution was added water (2 mL) and the precipitate was filtered, collected, and dried in vacuum to afford the title compound (41.2 mg, 75.0%) as a white solid. 1H NMR (DMSO-d6) δ (ppm): 10.48 (s, 1H), 8.13 (d, J=4.0 Hz, 1H), 7.57-7.76 (m, 3H), 6.80-7.02 (m, 3H), 4.50 (d, J=13.1 Hz, 1H), 3.84 (dd, J=11.4, 2.8 Hz, 1H), 3.35 (br. s., 2H), 3.22 (br. s., 4H), 2.79 (td, J=7.3, 3.9 Hz, 1H), 2.60 (td, J=12.6, 2.7 Hz, 1H), 2.46 (br. s., 4H), 2.03 (d, J=12.9 Hz, 1H), 1.83 (br. s., 1H), 1.64 (d, J=12.9 Hz, 1H), 1.31-1.57 (m, 3H), 0.61-0.69 (m, 2H), 0.48-0.56 (m, 2H). [M+H] calc'd for C26H32N6O2, 461; found, 461.
