Reaktionsschritte
The resultant compound from Example 73 (10.00 g, 36.93 mmol) and imidazole (5.40 g, 79.3 mmol) in acetonitrile (10 mL) were heated at reflux for 44 h. The mixture was evaporated and the residue was chromatographed on silica gel with 2% methanol in chloroform to afford 11.20 g (88%) of the desired product as an oil: TLC (5% methanol/95% chloroform) Rf =0.35; 1H-NMR (CDCl3) 7.38 (s, 1H), 7.38-7.05 (m, 10H), 7.00 (dd, 1H), 6.80 (dd, 1H), 5.03 (d, 1H), 4.99 (d, 1H), 4.25 (1H), 4.03 (dd, 1H), 3.22-3.09 (m, 1H), 3.02 (dd, 1H), 2.78 (dd, 1H).
