Procedure
To a solution of the aldehyde 47 (0.161 g, 0.359 mmol), 4-(2-morpholinoethoxy)aniline (0.120 g, 0.540 mmol), and dibutyltin dichloride (0.197 g, 0.648 mmol) in DMF (5 mL) was added a solution of phenylsilane (0.047 g, 0.434 mmol) in DMF (2 mL). The reaction mixture was stirred for 3 hours at RT and treated with a mixture of brine/sat. NAHCO3 solution. A precipitate was formed which was collected by filtration, washed with water and dried. Crude material was purified by flash column chromatography, eluent a 10 to 20% gradient of MeOH in AcOEt—to afford the title compound 331 (139 mg, 59.1% yield). 1H NMR (400 MHz, DMSO-d6) δ (ppm): 8.72 (s, 1H); 8.62 (d, J=1.6 Hz, 1H); 8.51 (dd, J=5.5 Hz, 1H); 8.30 (s, 1H); 8.22 (d, J=8.2 Hz, 1H); 7.88 (dd, J=8.2, 2.2 Hz, 1H); 7.73 (dd, J=13.5, 2.5 Hz, 1H); 7.38 (t, J=9.2 Hz, 1H); 7.20 (dd, J=8.8 1.2 Hz, 1H); 6.72-6.69 (m, 2H); 6.63 (dd, J=5.5, 0.8 Hz 1H); 6.58-6.54 (m, 3H); 5.95 (t, J=6.3 Hz, 1H); 4.30 (d, J=6.1 Hz, 2H); 3.82 (t, J=5.9 Hz, 2H); 3.55 (t, J=4.5 Hz, 4H); 2.60 (t, J=5.7 Hz, 2H); 2.57-2.62 (m, 1H); 2.42 (t, J=4.5 Hz, 4H); 0.68-0.63 (m, 2H); 0.47-0.41 (m, 2H).
