Participants

Reaction Steps

To a solution of potassium hydroxide (78.5 g, 1.4 mol), sodium hydroxymethylsulfinate (Rongalite®, 74.4 g, 0.63 mol) and the crude 5-amino-4-fluoro-2-methyl-benzenethiol (110 g, 0.7 mol) in 380 mL of DMF was added dropwise 2,2,2-trifluoroethyl iodide (147.1 g, 0.704 mol). The reaction mixture was stirred for 2 hours at room temperature, poured into water and then extracted with ethyl acetate. The organic phase was dried with sodium sulfate and concentrated under reduced pressure to yield the title compound (176 g, 99%).
