実験手順
Diethyl ({[3-(3,5-dimethyl-4-isoxazolyl)phenyl]amino}methylidene)-propanedioate (for a preparation see Intermediate 5, 75 g, 210 mmol) was suspended in boiling diphenylether (1 L) and heated to reflux for 30 minutes. The reaction mixture was cooled and precipitated with iPr2O to give the title compound as a brown powder (50 g, 76%). 1H NMR (300 MHz, DMSO-d6, ppm) δ: 12.45 (brs, 1H), 8.76 (s, 1H), 8.34 (d, J=8.6 Hz, 1H), 7.76 (s, 1H), 7.59 (d, J=8.6 Hz, 1H), 4.36 (q, J=7.1 Hz, 2H), 2.62 (s, 3H), 2.43 (s, 3H), 1.43 (s, J=7.1 Hz, 3H).
