実験手順
To dibenzofuran-2-carboxaldehyde (17) (200 mg, 1.02 mmol) was added solid NaOH (49 mg, 1.22 mmol) then 10% NaOH solution (1.8 mL). Silver nitrate (173 mg, 1.02 mmol) was then added, the reaction mixture heated to 60° C. for 1.5 hours and then stirred overnight at ambient temperature. The reaction mixture was then filtered and washed with water. The filtrate was acidified to pH 2 using concentrated HCl and the precipitated product filtered and dried to give the title compound as an off-white solid. Yield: 83 mg, 38%; LC-MS tr 1.31 min; HPLC Purity: 100%; MS (ES+) m/z not detectable (M+H)
