Reaction Steps

N-(4-(trifluoromethoxy)phenyl)ethanethioamide (38 g, 0.162 mol) was dissolved in EtOH (70 ml), water solution of NaOH (52.5 g, in 175 ml water) was added and the solution was diluted with 350 ml water. This solution was then added drop wise, within 30 min., into a solution of K2Fe(CN)6 (210 g) in 520 ml water at 85-95° C. The reaction mixture was then stirred at 85-95° C. for 1 hr and cooled. TLC (7:3-hexane:EtOAc) was performed. The product was extracted with DCM, the organic phase was dried over Na2SO4, filtered and evaporated and the residue was purified by flash column chromatography (5% EtOAc in hexane) to give 16.8 g (44.5%) of 2-methyl-6-(trifluoromethoxy)benzo[d]thiazole.
