Versuchsvorschrift

The title compound was synthesized by condensation of Intermediate 23 (250 mg, 0.690 mmol) with 2-(2-ethoxyethoxy)-3-methoxybenzaldehyde (204 mg, 0.970 mmol) in presence of sodium ethoxide (94 mg, 1.380 mmol) in ethanol (15 ml) according to the procedure outlined in Example 24 to give 178 mg of the desired product as a pale yellow solid; 1H NMR (300 MHz, DMSO-d6) δ 1.91 (t, J=6.9 Hz, 3H), 3.48-3.55 (m, 4H), 3.78 (s, 3H), 4.06 (br s, 2H), 6.81 (d, J=15.6 Hz, 1H), 6.92-6.94 (m, 1H), 7.00-7.02 (m, 1H), 7.55-7.57 (m, 2H), 7.61-7.64 (m, 2H), 7.84-7.87 (m, 2H), 8.07-8.09 (m, 1H), 8.23 (d, J=15.6 Hz, 1H), 8.84-8.87 (m, 1H); ESI-MS (m/z) 567.21 (M+H)+.
