실험 절차

(S)-3-(hydroxymethyl)-6a,7,8,9-tetrahydropyrido[3,2-e]pyrrolo[1,2-a]pyrazin-6(5H)-one (100 mg, 0.456 mmol), 3-chloro-N-cyclopropyl-4-(piperazin-1-yl)benzamide (128 mg, 0.456 mmol), (cyanomethyl)trimethylphosphonium iodide (166 mg, 0.684 mmol) and N,N-diisopropylethylamine (0.398 ml, 2.281 mmol) were suspended in propiononitrile (Volume: 1.370 ml) and heated in a closed vial at 90-120° C. for 4 h. The reaction mixture became a dark brown solution. It was cooled to room temperature, concentrated in vacuo, dissolved in DMSO (2 mL) and purified using HPLC (basic, 25-95% ACN in water, basic). The fractions were concentrated in vacuo and the resulting solid was recrystallized from water-MeOH (2:1, 15 mL) and dried in vacuum to afford (S)-3-chloro-N-cyclopropyl-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 (120.4 mg, 0.250 mmol, 54.9% yield) as an off-white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.50-0.60 (m, 2 H) 0.61-0.72 (m, 2 H) 1.84-2.01 (m, 3 H) 2.12-2.23 (m, 1 H) 2.51-2.57 (m, 4 H) 2.77-2.86 (m, 1 H) 3.02 (br. s., 4 H) 3.35-3.46 (m, 3 H) 3.54-3.64 (m, 1 H) 3.95-4.03 (m, 1 H) 6.98 (d, J=1.77 Hz, 1 H) 7.16 (d, J=8.34 Hz, 1 H) 7.63 (d, J=1.77 Hz, 1 H) 7.75 (dd, J=8.34, 2.02 Hz, 1 H) 7.85 (d, J=2.02 Hz, 1 H) 8.39 (d, J=4.04 Hz, 1 H) 10.45 (s, 1 H). [M+H] calc'd for C25H29ClN6O2, 481; found, 481.
