Versuchsvorschrift

A mixture of the product of Example 364A (24.2 g, 0.0678 mol), 4-amino-benzenethiol (12.7 g, 0.102 mol, 1.5 equiv.), and sodium acetate trihydrate (46.1 g, 0.339 mol, 5.0 equiv.) in 500 mL of ethanol was heated under reflux under nitrogen with stirring for 2 hours. The reaction mixture was then allowed to cool to room temperature and 200 mL of water added. The mixture was stirred for 30 minutes, filtered, and dried in vacuo to give the title compound (29.8 g, 99%).
