Versuchsvorschrift

To a mixture of 3-ethyloxazolidine-2,4-dithione 6 (79 mg, 0.49 mmol), 5-(2-methoxyphenyl)-2-furaldehyde 9 (99 mg, 0.49 mmol) and sodium acetate (201 mg, 2.45 mmol) was added acetic acid (5 mL). As more of the desired product was formed, the reaction mixture color turned to a very red solution. The reaction mixture was refluxed overnight, then the excess solvent was removed in vacuo. The residue was diluted with ethyl acetate (100 mL), then washed with water (2×20 mL). The organic layer was dried with brine and MgSO4, then concentrated in vacuo. Flash column chromatography afforded the desired product 2 (M103) in 95% yield (160 mg, purple solid).
