Acetic Anhydride → 1-(4-Phenylamino-5,7,8,9-tetrahydro-dipyrido[2,3-b;3',4'-d]pyrrol-6-yl)-ethanone

Participants

Reaction Steps

Phenyl-(6,7,8,9-tetrahydro-5H-dipyrido[2,3-b;3′,4′-d]pyrrol-4-yl)-amine (40 mg, 0.15 mmol), acetic anhydride (18 mg, 0.18 mmol), and triethylamine (0.06 mL, 0.45 mmol) were dissolved in 1,2-dichloroethane (2.0 mL), and stirred overnight at room temperature. The reaction mixture was added directly to a Biotage column. The crude product was purified via Biotage eluting with CH2Cl2/MeOH (9/1, v/v) to provide 8 (5 mg, 11% yield) as a tan solid. LC-MS (M+H=307, obsd.=307).
