Participants

Reaction Steps

3-Aminobenzonitrile (2.06 g, 17.4 mmol) was added to a solution of 3,4-diethoxy-3-cyclobutene-1,2-dione (2.97 g, 17.5 mmol) in absolute ethanol (50 mL). The mixture was heated at reflux overnight. The mixture was cooled and the resulting yellow precipitate was collected by vacuum filtration. Yield: 3.40 g (81%): 1H NMR (DMSO-d6): δ 10.95 (s, 1H), 7.75-7.40 (m, 4H), 4.73 (q, 2H), 1.39 (t, 3H).
