Sodium Carbonate → 3-Amino-N-(4-bromo-phenyl)-4-(4-hydroxy-phenylsulfanyl)-benzamide

Participants

Reaction Steps

A suspension of the product of Example 22A (409.9 mg, 0.9205 mmol) and iron powder (206 mg, 3.682 mmol) in acetic acid (7 mL) and ethanol (7 mL) was heated at reflux under a nitrogen atmosphere for 1 hour. The reaction was cooled to room temperature. The mixture was diluted with water (30 mL), the pH adjusted to 6 with solid sodium carbonate, and the aqueous extracted with ethyl acetate (2×50 mL). The combined organic extracts were washed with brine (25 mL), dried over sodium sulfate, filtered, and concentrated under vacuum to provide the title compound as a tan solid (290 mg, 0.6983 mmol, 76%).
