Versuchsvorschrift

To 5-phenyl-2-furaldehyde (35) (690 mg, 4.01 mmol) was added solid NaOH (176 mg, 4.40 mmol) then 10% NaOH solution (6.2 mL). Silver nitrate (680 mg, 4.00 mmol) was added and the reaction mixture heated to 60° C. for 4.5 hours then cooled to ambient temperature. The reaction mixture was then filtered and washed with water. The filtrate was acidified to pH 2 using 2N HCl and the precipitated product filtered and dried to give the title compound.
