Reaction Steps

(5-Chloro-benzo[1,3]dioxol-4-yl)-(6,7,8,9-tetrahydro-5H-dipyrido[2,3-b;3′,4′-d]pyrrol-4-yl)-amine (100 mg, 0.29 mmol) and DIEA (0.15 mL, 0.88 mmol) were dissolved in 1,2-dichloroethane (2 mL) and stirred at room temperature. Cyclopentanecarbonyl chloride (0.04 mL, 0.35 mmol) was added dropwise, and the reaction was stirred for 1 h at room temperature. The reaction was concentrated. The crude material was dissolved in DMSO (3 mL) and filtered. The filtrate was purified directly via prep-LC-MS to provide 70 (43 mg, 33% yield) as a white fluffy solid. LC-MS (M+H=439, obsd.=439).
