Versuchsvorschrift

A solution of the compound prepared in Example 214A (1.0 g, 3.80 mmol), 4-aminothiophenol (0.5 g, 4.00 mmol), cesium carbonate (1.3 g, 4 mmol) in dimethylformamide (10 ml) was heated at 40° C. for 16 hours. Afterwards, ice water (50 mL) was added to the solution and the resultant slurry was treated with ethyl acetate (100 ml). The layers were separated and the organic layer was washed with 10% sodium bicarbonate and 10% sodium chloride, then dried over anhydrous sodium sulfate. The drying agent was filtered and solvent was removed under vacuum leaving an orange oil as the title compound, (1.1 g, 83%).
