Procedure

(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 (75 mg, 0.22 mmol) and DIEA (0.11 mL, 0.66 mmol) were dissolved in 1,2-dichloroethane (2 mL) and stirred at room temperature. Isobutyryl chloride (0.03 mL, 0.26 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 72 (14 mg, 15% yield) as a white fluffy solid. LC-MS (M+H=413, obsd.=413).
