Hydrochloric Acid → HCID 118622746, compound

Participants

Reaction Steps

To a solution of 7-fluoro-5-methoxy-1,1-dimethyl-2,3-dihydro-1H-indene (4.76 g, 24.51 mmol) and 1-dodecanethiol (17.71 mL, 73.52 mmol) in toluene (50 mL) was added aluminium chloride (9.80 g, 73.52 mmol) at 0° C., and the mixture was stirred at room temperature for 2 hr. To the reaction mixture was added 1N hydrochloric acid, and the mixture was extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (solvent; ethyl acetate/hexane) to give 7-fluoro-1,1-dimethyl-2,3-dihydro-1H-inden-5-ol (4.17 g, 23.14 mmol, 94%) as an off-white solid.
