Versuchsvorschrift

To a solution of 1-oxa-6-thiaspiro[2.5]octane (6.33 g, 48.6 mmol) and 4′-hydroxy-2′,6′-dimethylbiphenyl-3-carbaldehyde (10.0 g, 44.2 mmol) in N,N-dimethylformamide (150 mL) was added potassium carbonate (6.11 g, 44.2 mmol) at room temperature, and the mixture was stirred at 100° C. for 12 hr. The reaction mixture was concentrated under reduced pressure, the residue was neutralized with 1 M hydrochloric acid, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was crystallized from diisopropyl ether to give the title compound (12.3 g, yield 78%) as colorless crystals.
