Participants

Reaction Steps

To a suspension of sodium hydride 60% w/w (0.12 g, 3.0 mmol) in 10 mL of DMF under the argon atmosphere was added slowly ethanethiol 98% (0.2 mL, 3.0 mmol), and the resulting solution was stirred for 15 min. A solution 6-bromo-7-methoxy-1,1,4-trimethyl-1,2-dihydronaphthalene (Compound 93, 0.24 g, 0.84 mmol) in 2 mL of DMF was added, and the reaction mixture was refluxed for 4 h, then cooled to room temperature, acidified with 2 N HCl, diluted with water and extracted with ethyl acetate. The combined extracts were washed with brine, dried over MgSO4, and filtered. The solvent was removed to afford 0.23 g (100%) of the title compound as a clear oil.
