実験手順

To a solution of 2-(3-methoxyallylidene)malonic acid dimethyl ester (Acros Organics, 200 mg, 1.0 mmol) in THF (2 mL) at rt was added aniline (300 mg, 3.2 mmol) and the reaction mixture was heated at 60° C. for 8.5 h. Purification of the reaction mixture by preparative HPLC provided the desired product (150 mg, 57%) as a yellow solid. 1H NMR (DMSO-d6) δ 10.16 (d, 1H, J=12.7 Hz), 8.06 (t, 1H, J=12.7 Hz), 7.74 (d, 1H, J=12.7 Hz), 7.30 (t, 2H, J=8.7 Hz), 7.16 (d, 2H, J=7.7 Hz), 6.98 (t, 1H, J=7.7 Hz), 6.35 (t, 1H, J=12.1 Hz), 3.69 (s, 3H), 3.65 (s, 3H).
