الإجراء التجريبي

(S)-4-(4-((6-oxo-5,6,6a,7,8,9-hexahydropyrido[3,2-e]pyrrolo[1,2-a]pyrazin-3-yl)methyl)piperazin-1-yl)benzoic acid (87.0 mg, 0.214 mmol) and propan-2-amine (18.93 mg, 0.320 mmol) were suspended in DMF (1 ml) and treated with DIPEA (0.186 ml, 1.068 mmol) and 2-(3H-[1,2,3]triazolo[4,5-b]pyridin-3-yl)-1,1,3,3-tetramethylisouronium hexafluorophosphate(V) (162 mg, 0.427 mmol). The reaction mixture was stirred at room temperature for 3 h and purified using HPLC (25-95% acetonitrile in water, NH4HCO3 buffered) to afford (S)—N-isopropyl-4-(4-((6-oxo-5,6,6a,7,8,9-hexahydropyrido[3,2-e]pyrrolo[1,2-a]pyrazin-3-yl)methyl)piperazin-1-yl)benzamide (39.6 mg, 0.088 mmol, 41.3% yield) as an off-white solid. 1H NMR (400 MHz, DMSO-d6) δ (ppm): 1.13 (d, J=6.57 Hz, 6 H) 1.85-2.00 (m, 3 H) 2.11-2.24 (m, 1 H) 2.41-2.48 (m, 4 H) 3.17-3.27 (m, 4 H) 3.34-3.44 (m, 3 H) 3.53-3.65 (m, 1 H) 3.93-4.13 (m, 2 H) 6.91 (d, J=9.09 Hz, 2 H) 6.99 (d, J=2.02 Hz, 1 H) 7.62 (d, J=2.02 Hz, 1 H) 7.72 (d, J=9.09 Hz, 2 H) 7.89 (d, J=7.83 Hz, 1 H) 10.44 (s, 1 H); [M+H] calc'd for C25H32N6O2, 449; found, 449.
