Participants

Reaction Steps

Into a 50-mL round-bottom flask, was placed a solution of methyl 3-(4-aminopiperidin-1-yl)-2-phenylquinoxaline-6-carboxylate (100 mg, 0.28 mmol, 1.00 equiv) in dichloromethane (50 mL). This was followed by the addition of triethylamine (7 mL) and acetic anhydride (1 mL) at 0° C. The resulting solution was stirred overnight at room temperature and concentrated under vacuum. This resulted in 0.1 g (90%) of methyl 3-(4-acetamidopiperidin-1-yl)-2-phenylquinoxaline-6-carboxylate as light yellow oil.
