4-Aminothiophenol → HCID 66808383, compound

Participants

Reaction Steps

A mixture of the product of Example 149A (500 mg, 1.277 mmol), 4-aminothiophenol (240 mg, 1.915 mmol) and anhydrous sodium acetate (524 mg, 6.384 mmol) in anhydrous ethanol (9 mL) was heated at reflux under a nitrogen atmosphere for 1 hour. The reaction was cooled to room temperature and the ethanol removed by rotary evaporation under vacuum. The residue was taken up in ethyl acetate (100 mL) and washed with water (2×50 mL) and brine (50 mL). The organic phase was dried over anhydrous sodium sulfate, filtered, and concentrated under vacuum, co-evaporating the oil with methylene chloride/hexanes to obtain the title compound as an orange foam (613 mg, 100%).
