Reaction Steps

Zinc powder (3.1 g) was added to a suspension of p-trifluoromethoxybenzenesulfonyl chloride (1.36 ml) in concentrated sulfuric acid (3.4 ml) and water (20 ml), and the suspension was stirred at 0° C. for 18 hours and heated under reflux for 6 hours. The mixture was added with ethyl acetate, washed with water, saturated aqueous solution of sodium hydrogen carbonate, and saturated brine, and then concentrated under reduced pressure to give p-trifluoromethoxybenzenethiol (0.73 g, 47%).
