Versuchsvorschrift

The title compound was synthesized by condensation of Intermediate 5 (400 mg, 1.289 mmol) with 2-cyclobutylmethoxy-3-methoxybenzaldehyde (368 mg, 1.603 mmol) in the presence of sodium ethoxide (163 mg, 2.411 mmol) in ethanol (15 ml) according to the procedure described in Example 24 to give 310 mg of the desired product as an off-white solid; 1H NMR (300 MHz, DMSO-d6) δ 1.80-1.86 (m, 5H), 1.98-2.04 (m, 2H), 3.77 (s, 3H), 3.82 (d, J=6.9 Hz, 2H), 6.87-7.00 (m, 4H), 7.51 (d, J=7.5 Hz, 1H), 7.59 (d, J=7.8 Hz, 2H), 7.84 (d, J=7.8 Hz, 2H), 8.01 (d, J=4.8 Hz, 1H) 8.14 (d, J=15.6 Hz, 1H); ESI-MS (m/z) 513.30 (M+H)+.
