Versuchsvorschrift

A solution of N-(3-Bromo-phenyl)-4-chloro-3-nitro-benzamide (from Example 26A) (0.356 g, 1.0 mmol), 3-hydroxythiophenol (0.126 g, 1.0 mmol) and cesium carbonate (0.65 g, 2.0 mmol) in N,N-dimethylformamide (5 mL) was heated to 95° C. for 3 hours. After cooling to room temperature the mixture was poured into ice water (20 mL) and the resultant solution acidified with 1N aqueous hydrochloric acid. The solution was then extracted with ethyl acetate (3×10 mL), the combined extracts dried over magnesium sulfate, filtered and concentrated under vacuum to provide the title compound (0.430 g, 97%).
