反応手順

(Z)-5H-Dibenzo[b,f]azepine (100 mg, 0.52 mmol), dibutyltin dichloride (54 mg, 0.16 mmol) and methyl 4-formylbenzoate (260 mg, 1.60 mmol) were stirred in THF (2 mL) for 30 minutes. Phenylsilane was added and the reaction mixture was stirred for 3 days. The solvent was evaporated and the residue was purified by flash chromatography (0% to 40% EtOAc in hexanes). The fractions containing some product were washed with Na2S2O4. The layers were split and the organic layer was evaporated to afford title compound 350 (147 mg, 83%) as a yellow solid.
